Overview of Mammography and its Importance

Overview of Mammography and its Importance Mammography is the radiographic imaging of the breasts. It is a special diagnostic and screening tool of the human breasts. A mammography is done with specific x-ray equipment which is able to find tumors too small to be felt. Mammography examinations ultimate goal is the early detection of breast cancer, typically through detection of characteristics masses and / or micro calcifications. A mammogram is the best radiographic method available for early breasts cancer detection. It is ideal and indispensable for women above the age of 40 years old, for whom the risk of breast cancer is increased. Like x-rays, mammogram uses doses of ionizing radiation to create images but at lower dose amplitude-x-rays (most often around 0.7mSv). Radiologists then analyze the produced images for any abnormalities. A longer wavelength x-rays (typically Mo-K) is normally used for mammogram compared to those used in radiography of bones. Like many other medical tests, mammograms are not 100% accurate. The refore, a regular mammogram scheduling is needed to detect any early breasts changes before any obvious signs or symptoms show up. It is also scientifically proven that mammogram can reduce breast cancer mortality rate by more than a third. Despite its function in early detection of breast cancer, mammography has a false-negative (missed cancer) rate of at least ten percent. This is due to the dense tissue obscuring the cancer and the large overlap of cancer appearance in mammograms with normal tissues appearance. Mammography first started in 1960s. However, modern mammography has only existed since 1969 when the first x-ray unit dedicated to breasts imaging was made available to the public. Such examination as a screening device became standard practice by the year of 1976. Mammography then continues to improve as lower dose of radiation able to detect smaller potential problem earlier. Throughout the years, mammography has made advances to further improve its diagnostic ability. Digital mammography and computer aided detection are two examples of recent advances in the field of mammography. Digital mammography, also known as full field digital mammography (FFDM), is a mammography system in which solid-state detectors that convert x-rays to electrical signals replace the conventional x-ray film. These detectors are similar to those found in digital cameras where electrical signals produced are used to create images of breasts which are then projected on a computer screen or printed on a speci al film similar to conventional mammograms. A digital mammogram is essentially the same as a conventional film screen mammogram. Computer aided detection (CAD) systems help to detect abnormalities by using computer software. A digitized mammographic image that can be obtained either from a digitally acquired mammogram or a conventional film mammogram is used by the computer aided systems. The computer software then searches for abnormal areas of mass, density or calcification that may indicate the presence of cancer. It highlights the abnormal areas on the images, alerting the radiologists to the need of further analysis. A special mammography machine is used for the screening of breasts. The machine comprises of an x-ray tube connected to a breasts support which houses the film cassette or imaging device on a C shaped arm, with moveable compression paddle between the two. There are few standard functional requirements for the mammography machine in order to produce a good quality image. The high voltage generator of mammography machine shall supply a near direct current high voltage with ripple less than 5 percent. Most modern mammography machines have a automatic selection for kilo voltage (kVp) output in order to optimize contrast. The generator produces a constant potential and the high voltage applied to the tube must be from 22 to 35kVp in increments of 1kVp. The focal spot size of mammography machine should be as small as possible to ensure adequate resolution. A focal spot size of 0.3mm is recommendable for general mammography and 0.1mm (small focus) for magnification views. The tube current o f mammography machine should be set as high as possible in order to minimize exposure time and thus reducing the likelihood of motion artifact. A moving grid with grid factor of less than 2.5 at 30 kVp is essential to ensure optimum image quality. An automatic exposure control (AEC) is important in mammography machine. This is due to the wide variation in breasts sizes and compositions. There is little scope for mAs selection errors as there is a need for high radiographic contrast and consequently the system has low latitude. As for image recording material, most of the mammography facilities are still utilizing traditional cassettes, intensifying screens and single emulsion film with processing being taking place. Mammography usually uses cassette containing a single intensifying screen and the film which is usually green sensitive has a single emulsion layer. Both these equipment are essential to give optimum resolution. A mammography film requires high spatial resolution. It sho uld has enough speed to ensure that the dose is acceptable without being so fast that it causes visible quantum mottle and high contrast with enough latitude to show both dense glandular tissue and the skin edge. Quality control, assurance programs and strict processing parameters are vital to ensure the standard in film quality is not compromised. Any reduction in film quality may lead to misinterpretation of image and incorrect diagnosis. In the modern days, digital mammography is slowing making its way to the imaging field. This modern modality has some advantages over the conventional film mammography. The examination time and time between examining patients decreases as chemical processing and changeover of cassette is no longer necessary. Markers can be applied on image digitally. Images produced can also be manipulated. One of the major advantages of image manipulation is the ability for image magnification with significantly less unsharpness compared to those associated with macro or magnification images that are sometimes required to demonstrate suspicious areas already seen on mammograms. Unlike the conventional magnification views, digital magnification does not involve an additional exposure to radiation. Patients are required to do some preparations prior to a mammography examination. Fasting or observation in particular dietetic rules days before mammogram examination is not necessary. However, for women sensitive to caffeine, they shall refrain from taking caffeine containing products such as cola, chocolate and coffee two weeks before undergoing the test. This is because caffeine could make the breasts more tender which may affect the quality of radiograph. Menstrual cycle phase usually does not affect the outcome of the examination. However, it is also highly recommendable to schedule for mammogram one week following patients menstrual cycle. This is so as the breasts are less tender compared to that during pre-ovulatory and postovulatory period (half cycle) as well as during premenstrual period. It is also advisable for patients to wear two piece clothing on examination day to ease the undressing process for mammogram. Cosmetics, oils, creams, lotion and talc or deodorant must n ot be applied hours prior to test at the underarms and breasts areas. Failure in doing so may result in those appearing in mammogram as calcium spots. Patients are also encouraged to bring along all previous mammograms for comparison purposes by the radiologist. Most often, mammograms are done on older patients compared to younger patients. this is due to the breast tissue changes during life. The breast tissue density in younger women often makes mammogram rather difficult to interpret. However, as women age increases, some changes in the structure of breasts occurs as glandular and fibrous tissues reduce in size and this results in breasts tissues become more fatty. On the examination day, a simple interview with the patients is conducted before the examination takes place. They will be asked on any prior surgeries history, family or personal history of breasts cancer as well as hormone use. It is also the responsibility of the radiographer or technologist to enquire the patients last menstrual period as to determine whether the patient is pregnant. Pregnant patients are not recommendable for such examination. Upon completion of the short interview, patients are then ushered to change into hospital gown and remove all potential artifact before proceeding for the examination. When the examination takes place, the breast is compressed using compression paddle on the mammography unit. A parallel plate compression evens out the breast tissue. Compression of breast reduces the thickness of tissue that x-rays penetrate, decreases the amount of scattered radiation, and reduces the required radiation dose and holding the breast (remove movement unsharpness) still and thus improving the image quality. Both craniocaudal, CC view (head to foot) and mediolateral oblique, MLO (angled side view) of the breast are taken in screening mammography. Extra views such as geometrically magnified and spot-compressed views of particular area of concern may be taken in diagnostic mammography. While performing the craniocaudal (CC) view, the mammography unit is positioned with the breast support table (image receptor holder) horizontal and the height adjusted to slightly above the level of patients inframammary angle. The patient is then instructed to face the machine, standing w ith approximately 5-6cm back, feet facing the machine but body rotated 15-20Â ° away from the side under examination. This is so that the breast under examination is brought closer to the image receptor holder and aligned with the center of it. The patients arms hang loosely by her side and head is turned away from the side to be examined. The breast is then lifted gently up and away from the chest wall of patient. While supporting the breast, the height of the machine is adjusted so that the image receptor holder makes contact with the breast at the inframammary fold and the breast is approximately 90Â ° to the chest wall. The breast is then carefully placed in contact with the cassette. Hand is then slowly removed from the breast, whilst ensuring that no skin folds are created underneath the breast. Patients arm of the side under examination is then flexed at the elbow and the hand is placed on the patients lower abdomen or relaxed at the side of the trunk. This relaxes the pect oral muscle. Patients shoulder is gently pressed down to bring the outer quadrant of the breast into contact with the image receptor. Slight pressure is maintained at the patients back to ensure she does not inadvertently pull back from the unit and cause some tissue to be lost from the resultant image. Radiographers thumb is then placed n the medial aspect and middle finger on the superior aspect of the breast, gently pulling forward towards the nipple while the compression is applied slowly. Radiographers other hand is placed on the patients shoulder of the side being examined to ensure that it stays relaxed. The light beam diaphragm can be used during the application of compression. This is to ensure the nipple is in profile, all breast is included in the main beam, both medial and lateral margins are included, no skin folds and an adequate breast compression. A CC marker with left or right identifier is positioned on the axillary edge of the cassette, within the primary beam. Pa tient is strongly advised not to move and the projection is done quickly after that. The same CC procedure is performed on both left and right breast. The CC view with the same procedure is performed on patients both breasts. Besides the CC view, a mediolateral oblique (MLO) view of patients both breasts is also taken for screening mammogram. The positioning of patients for left breast MLO view is to have patient facing the mammography unit with feet pointing towards it. From the position used for CC projection, the unit is rotated through 45Â ° with the x-ray tube on patients right and the beam angled caudally. The height is adjusted to bring the lower border of cassette 2.5cm below the inferior portion of the left breast. It may be necessary to further adjust the height during patient positioning. The lateral edge of the left of the thorax is in line with the image receptor holder so that the left breast also lies next to it. The radiographer then stands behind and slightly to the right of patient. Patient is then asked to raise her left arm and chin. The raising of chin may prevent the superimposition of the mandible over the breast. Patients left breast is then held with right hand and patient is kep t in position by holding on to the right shoulder. Patient who is advised to lean forward into machine with feet still facing forward is asked to lean slightly laterally. The left axilla of patient should lie over the corner of image receptor that is nearest to chest wall. Radiographer then proceeds to life the posterior skin edge of the left axilla to prevent skin folds from occurring. Patients left arm is then pulled across and behind the image receptor holder. Patients elbow is also flexed so that the forearm can be placed on the unit for support and elbow is positioned so that it hangs down comfortably behind the holder. The humeral head is gently pushed forward and the corner of image receptor lies in the axilla, anterior to posterior fold. While the patient maintains the position, radiographer double check to ensure there is no skin fold in the axilla or under the lateral aspect of the breast and to check for and remove any creases at the inframammary angle. The breast is then lifted up and away from the chest wall while holding the patients left shoulder. The breast is then placed on the image receptor and compression is applied. Projection on the left breast is then taken. The same MLO view projection is then repeated vice versa on the right breast of patient. Upon completion of the examination, patient is advised to change back to her clothes. Patient is then escorted out and at the same time patient is informed on her next appointment for the review of results with the radiologist. Any discussion on the results with patient prior to the review of radiologist is prohibited. Mammography has been long known to be an effective modality for breast screening. Such examination improves physicians ability to detect small tumors and early treatment can be performed to reduce mortality rate. Mammogram is also the only proven method to reliably detect tumors as well as all types of breast cancer, including invasive ductal and invasive lobular cancer. Radiation used in mammography examination is of low dosage and usually has no side effects towards patient. Moreover, radiation does not remain in patients body after the examination. Despite its benefits in the purpose of screening and diagnostic, mammography poses certain risks towards its patients. There is a slight chance of cancer from excessive exposure to radiation. The effective radiation dose for this procedure varies depending on the thickness of tissue. However, radiographers are trained to use the lowest radiation dose possible for radiation protection purposes while producing the best images for evaluati on. False positive mammogram is also one of the risks in performing mammogram. Five percent to 15 percent of screening mammograms need more testing such as additional view for mammograms or ultrasound to further determine suspected abnormality. Most of the further tests turn out to be normal. However if there is an abnormal finding, biopsy may be performed on the patient to determine whether the tumor is benign or malignant. Women above the age of 40 are normally advised for a mammogram annually as they pose a higher risk of being diagnose with breast cancer. However, an ultrasound is more preferably performed on patients below the age of 40 as their breasts tissue is denser. Last but not least, women of all age should go for routine breast check up regularly for early detection on any breast abnormalities.

Ethical Dilemmas of Genetic Prenatal Screening Essay -- Genetic Testing

One of the questions that has recently plagued me has been that of which is about the genetic structuring of our offspring. I ask myself, will we able to choose the physical features our child? If so, do we as a society think this will be an ethical practice? Perhaps, scientifically, this might be entirely possible, but law will most likely restrict it. An article written by Frederic Golden helped me draw some understanding on this hot topic. Golden commences his article with a brief story of a mother and father who have been through prenatal testing. They tested for Down syndrome and an inheritable neuromuscular disease. While it was a straightforward procedure that was deemed valid by their doctor, Blue Cross (their insurance provider) refused to pay the bill, even though it was only $300. â€Å"It often opens up a Pandora’s box of questions that tear not only into pocketbooks but our psyches: What if the news from a test is bad?

Spanish Painters :: essays research papers

Spanish painter, the country's greatest baroque artist, who, with Francisco de Goya and El Greco, forms the great triumvirate of Spanish painting. Velà ¡zquez was born in Seville on June 6, 1599, the oldest of six children; both his parents were from the minor nobility. Between 1611 and 1617 the young Velà ¡zquez worked as an apprentice to Francisco Pacheco, a Sevillian Mannerist painter who became Velà ¡zquez's father-in-law. During his student years Velà ¡zquez absorbed the most popular contemporaneous styles of painting, derived, in part, from both Flemish and Italian realism. Many of his earliest paintings show a strong naturalist bias, as does The Meal, which may have been his first work as an independent master after passing the examination of the Guild of Saint Luke. This painting belongs to the first of three categories—the bodegà ³n, or kitchen piece, along with portraits and religious scenes—into which his youthful works, executed between about 1617 and 1623, may be placed. In his kitchen pieces, a few figures are combined with studied still-life objects, as in Water Seller of Seville. The masterly effects of light and shadow, as well as the direct observation of nature, make inevitable a comparison with the work of the Italian painter Caravaggio. Velà ¡zquez's religious paintings, images of simple piety, portray models drawn from the streets of Seville, as Pacheco states in his biography of Velà ¡zquez. In Adoration of the Magi, for example, the artist painted his own family in the guise of biblical figures, including a self-portra it as well. Velà ¡zquez was also well acquainted with members of the intellectual circles of Seville. Pacheco was the director of an informal humanist academy; at its meetings the young artist was introduced to such people as the great poet Luis de Gà ³ngora y Argote, whose portrait he executed in 1622. Such contact was important for Velà ¡zquez's later work on mythological and classical subjects. In 1622 Velà ¡zquez made his first trip to Madrid, to see the royal painting collections, but more likely in an unsuccessful search for a position as court painter. In 1623, however, he returned to the capital and, after executing a portrait of the king, was named official painter to Philip IV. The portrait was the first among many such sober, direct renditions of the king, the royal family, and members of the court. Indeed, throughout the later 1620s, most of his efforts were dedicated to portraiture. Mythological subjects would at times occupy his attention, as in Bacchus or The Drinkers.

Teens and Premarital Sex :: Sexual Education Pregnancy Marriage

The Impure Waterwheel Have you ever seen a watermill? Turning continuously, they are bound in an eternal cycle. Continually spinning,, the lack of purity in the United States can be compared to that watermill, a never-ending cycle that threatens to spin out of control. We must intercede. Sex out of wedlock creates dysfunctional families, and teens searching for â€Å"more† in life, who often turn to the reason they're feeling so glum, sex. Having sex out of wedlock is a big problem in the United States that needs to stop. Strained by relationships on the verge of collapse and peer pressure, many teens turn to sex as an escape. Hardly sixteen, Jamie Lynn Spears is an excellent example of how family problems can pressure someone to do things they know they shouldn’t. Jamie Lynn’s sister, Brittany Spears, is undergoing extensive criticism from the media about her recent mental breakdown, this pressure from the paparazzi has taken its toll on Jamie Lynn’s life and she made a bad choice, as so many young people today do. With the baby, that so often follows sex out of wedlock many times a â€Å"family† is quickly formed out of girlfriends and boyfriends who think they’re â€Å"in love†. In many cases, one of the parents will leave, forming yet another dysfunctional family. Dysfunctional families are often unloving and make childhood difficult. Wrestling with their own problems many single parents will simply hang their children out to dry. Basically neglected, children deem themselves extremely reviled and not good enough. Off this assumption of worthlessness, many young people will label or allow themselves to be labeled as â€Å"unloved†. Hated by their parents, or at least feeling they’re hated, teens will go to extensive lengths to find self-worth. While they realize they will never be able to replace their parent’s love, adolescents will always try to find meaning. Teens will search for something â€Å"more† in life, which they never got in their childhood always. If they feel they can’t earn their parent's love young people will turn to other things to satisfy their need to be accepted. Grossly, many teens turn to drugs or alcohol to try to forget their life. Tortured by life, some people turn to popularity to appease their soul, but none of these alternatives can. Craving love, many teens turn to sex as an alternative to facing reality, or simply as a place to find the love they’ve never felt.

Benjamin Franklin…A Misogynist? Essay

You asked us to read â€Å"Old Mistresses Apologue† to see how Benjamin Franklin begins as a solemn friend and adviser to a young man but soon reveals himself as a hedonistic lecher, then after reading you asked if we see any signs of a misogynist in Benjamin Franklin’s letter. To begin I looked up the word misogynist to get a better understanding of what it meant. According to Webster’s Dictionary, misogynist means a hatred of or hostility toward women, a women hater. After reading Benjamin Franklin’s letter, it was hard to see Mr. Franklin as a women hater. I find him being finicky about his women preferring older to younger women being almost discriminatory towards younger women in general, but not actually a women hater. If anything, he has good things to say about women as a whole. In the very first paragraph of his letter, Benjamin Franklin says great things of women in the state of union with a man. First, he states that â€Å"It is the Man and Woman united that make the compleat human Being.† [sic] Those are powerful word to say if you are a women hater. He also states in the same paragraph that man would be of less value if they were not married and they are incomplete without their better half. Hence his words, â€Å"A single Man has not nearly the Value he would have in that State of Union. He is an incomplete Animal. He resembles that odd Half of a Pair of Scissars.† [sic] Beginning after the first paragraph Benjamin Franklin begins stating increasingly how he would prefer an older woman to a younger one saying; â€Å"you should prefer old Women to young ones.† [sic] Then he proceeds to explain why he believes this theory with eight different reasons. The very first point, Franklin explains that older women are better because they are smarter, more experienced and can hold a conversation that is more interesting than that of a younger women. In his second point, he explains how when women get older they can do more for you and take better care of you. He even states that â€Å"there is hardly a thing as an old woman who is not a good Woman.† [sic] Therefore, if Benjamin Franklin was a misogynist I hardly think he would have stated that women were even good in any right. Benjamin Franklin’s fourth point explains how older women are less likely to stray and if they did it would be more accepted by an older woman than a younger one. Since older women are so willing to take care of younger man and help to shape his values and manners. This can be seen best in this line, â€Å"Because thro’ more Experience, they are more prudent and discreet in conducting an Intrigue to prevent Suspicion.† [sic] Now in Benjamin Franklin’s fifth point I see him saying something that can be seen as misogynist comment, â€Å"and regarding only what is below the Girdle, it is impossible of two Women to know and old from a young one. And as in the dark all Cats are grey.† [sic] That comment to me can be taken as an insult to women, I don’t think that everything below the â€Å"girdle† or waist is what makes all women young and old alike, but I do see Franklin’s point. Now lastly, my favorite comment had to have been in his eighth point when he states that older women are better to marry than young ones because, â€Å"They are so grateful!!† That comment in it self should be an indication that Benjamin Franklin was not a misogynist, he may have said one or two things that can be taken that way. Nevertheless, Franklin seems to like women in general he definitely had more nice things to say about women than anything else, almost as though he couldn’t be without a woman.

Abortion in the United States Essay
