Which mammography view displays the pectoral muscle, retromammary tissue, and nipple in profile?

  1. Mediolateral Oblique View

  2. Craniocaudal View

  3. Lateral View

  4. 45-Degree View

The correct answer is: Craniocaudal View

The craniocaudal view is specifically designed to provide a clear visualization of the breast structure, particularly highlighting the pectoral muscle, retromammary tissue, and nipple in profile. In this view, the x-ray beam is directed from above the breast downwards toward the detector, allowing for an optimal representation of these anatomical features. The positioning in the craniocaudal view ensures that the pectoral muscle is displayed prominently along the posterior aspect of the breast, while the retromammary fat layer is seen immediately adjacent to it. Additionally, the nipple appears in profile, which is critical for assessing its appearance and any potential abnormalities. This combination of visibility for the pectoral muscle, retromammary tissue, and the nipple is distinctive to the craniocaudal view, making it an essential perspective in mammographic imaging for detailed evaluation of breast structures. Other views, while useful for various assessments, do not provide the same comprehensive profile of these specific anatomical features simultaneously.
