What best describes the CC and MLO projections in capturing breast tissue?

The choice describing the CC (Cranio-Caudal) and MLO (Medio-Lateral Oblique) projections as complementary accurately captures their roles in mammography for capturing breast tissue.

The CC projection is designed to provide a direct, top-down view of the breast, allowing for an effective assessment of lesions or calcifications located in the central and upper regions. By orienting the breast in this manner, the CC view reveals tissue density and structures that are critical for diagnosis.

On the other hand, the MLO projection is crucial for visualizing the lateral aspects of the breast. This projection's angled orientation allows the examination of a broader area of breast tissue, particularly the outer breast and the axillary region, which are often difficult to visualize using a CC view alone.

Together, these projections work in a complementary manner to maximize the amount of breast tissue visualized and to enhance the detection of abnormalities. By capturing the breast from different angles, they provide a more comprehensive view, which is essential for effective screening and diagnostic evaluation. Hence, describing them as complementary is accurate as they each fulfill unique roles while collectively contributing to a more thorough assessment of breast tissue.
