Which portion of the breast is excluded during the performance of the CC projection?

The CC (Cranio-Caudal) projection is a standard mammographic view that captures the breast tissue from the top down, allowing radiologists to visualize and evaluate the glandular tissue effectively. In the CC projection, the focus is on visualizing the anterior and central portions of the breast, while the more superficial and posterior sections may be somewhat less visualized or excluded from the final imagery.

This is primarily due to the positioning of the breast during the exam, which compresses the tissue to obtain a clearer view of the lesions and surrounding anatomy. The posterior and superior tissue might not be imaged adequately during the CC view, as the alignment and angle of the X-ray beam can cause these areas to be less represented.

It is important for professionals interpreting these images to understand that this specific projection may not comprehensively capture all areas of breast tissue, particularly the posterior and superior aspects, which could be crucial for thorough evaluation and diagnosis. Therefore, the correct answer emphasizes the exclusion of these areas during the CC projection.
