CAMRT Radiography Practice Exam

Which two projections are routine for mammography imaging?

1. MLO and CC

2. AP and Lateral

3. CC and Oblique

4. Lateral and Mediolateral

The correct answer is: MLO and CC

In mammography, the two standard projections that are routinely performed are the mediolateral oblique (MLO) and the craniocaudal (CC) views. The mediolateral oblique view is crucial because it provides a comprehensive assessment of the breast tissue, allowing visualization from the top and side. This projection takes advantage of the anatomical layout of breast tissue, capturing details about the upper and outer quadrants, which is where a high percentage of tumors traditionally occur. The angled positioning helps to reduce superimposition of the structures within the breast, enhancing the ability to detect abnormalities. The craniocaudal view, on the other hand, presents the breast from a superior to inferior perspective. This projection gives a clear view of the breast and is essential for identifying masses or abnormalities present within the breast tissue. It effectively captures the thickness of the breast as a whole. Both these projections are essential for a thorough mammographic examination because together they provide a comprehensive view of the breast tissue, increasing the likelihood of detecting cancerous changes or other abnormalities. They also facilitate the comparison during follow-up imaging or assessments, making them foundational to breast cancer screening protocols.
