What projection can best demonstrate details of the medial breast tissue?

The best projection to demonstrate details of the medial breast tissue is the combination of cranio-caudal (CC) and lateral medial (LM) views. The CC view provides a direct perspective of the breast tissue from above, allowing for the evaluation of the overall morphology and any abnormalities. The LM view complements this by allowing visualization from the lateral aspect and can help distinguish structures more clearly in the medial region of the breast.

In the context of mammography, understanding the anatomy of the breast is crucial for accurate diagnosis. The CC view is excellent for visualizing the breast's anteroposterior dimensions, while the LM view allows for better delineation of the medial structures. When combined, these projections provide a comprehensive view that is effective for assessing the medial breast tissue in detail.

Other options may combine views that do not specifically target the medial aspect as effectively as the CC and LM. For instance, projections like MLO and AT may focus on different angles that do not prioritize the medial tissue's visibility and assessment. Thus, the CC and LM views are optimal for this purpose.
