Abstract
Breast imaging is a sub-speciality of diagnostic radiology that involves imaging of the breasts for screening or diagnostic purposes. There are various methods of breast imaging using a variety of technologies as described in detail below. Traditional screening and diagnostic mammography uses X-ray technology. Breast tom synthesis is a new digital mammography technique that produces 3D images of the breast using X-rays, Xeromammography and Galactography also use X-ray technology and are also used infrequently in the detection of breast cancer. Breast ultrasound is another technology employed in diagnosis & screening and specifically can help differentiate between fluid filled and solid lumps that can help determine if cancerous, Breast MRI is, yet, another technology reserved for high-risk patients and can help determine the extent of cancer if diagnosed, Lastly, scintimammography is used in a subgroup of patients who have abnormal mammograms or whose screening is not reliable on the basis of using traditional mammography or ultrasound.
Mammography
Overall has a false-positive rate of approximately 10%.It has a false-negative (missed cancer) rate of between 7 and 12 percent. This is partly due to dense tissues obscuring the cancer and the fact that the appearance of cancer on mammograms has a large overlap with the appearance of normal tissues. Additionally, mammogram should not be done with any increased frequency in people undergoing breast surgery, including breast enlargement, mastopexy, and breast reduction.
Digital Breast Tomosynthesis (DBT)
Digital breast tomo synthesis (DBT) can provide a higher diagnostic accuracy compared to conventional mammography. The key to understanding DBT is analogous to understanding the difference between an X-ray and CT. specifically; one is three dimensional whereas the other is flat. A mammogram usually takes two X-rays of each breast from different angles whereas digital tomosynthesis creates a 3-dimensional picture of the breast using X-rays
