Which projection best demonstrates the maximum amount of breast tissue?

1. CC

2. MLO

3. Lateral

4. Radial

The correct answer is: MLO

The MLO (mediolateral oblique) projection is recognized for its effectiveness in demonstrating the maximum amount of breast tissue. This technique involves positioning the breast at an angle that optimally includes both the medial and lateral aspects of the breast, providing a comprehensive view. By angling the X-ray beam obliquely, the MLO projection allows for better visualization of areas that might be obscured in other projections, such as the axillary tail and the inner portions of the breast. This projection is particularly important for screening and diagnostic purposes because it maximizes tissue inclusion, which can aid in identifying abnormalities. It encompasses a significant portion of the breast while also maintaining a balance of breast architecture and density. Other projections, while useful, do not achieve the same level of tissue coverage. The CC (craniocaudal) projection, for instance, provides a good view of the breast but does not include as much peripheral tissue compared to the MLO view. The lateral projection focuses on a specific area but lacks in full representation of the breast anatomy. The radial projection, often used for specific evaluations, is less utilized for general examination and also does not encompass as much of the breast tissue. Therefore, the MLO projection is optimal for obtaining a
