Which projection enhances the detail of a lesion located in the medial portion of the breast?

The ML (Medial-Lateral) projection is particularly effective in enhancing the detail of lesions located in the medial portion of the breast. This projection is angled to capture the breast tissue in a manner that brings the medial structures into clearer focus, effectively minimizing superimposition from adjacent anatomical structures and providing a more distinct view of the area of interest.

In a typical mammographic examination, positioning is crucial for obtaining the best visualization of lesions. The ML projection allows the radiologist to evaluate lesions in the medial aspect of the breast more accurately, as it presents the medial tissue more prominently without interference from structures that could obscure findings. By leveraging this technique, the visibility of potential abnormalities is improved, leading to better diagnostic accuracy.

Other projections, such as the MLO (Mediolateral Oblique) and CC (Craniocaudal), although useful in their respective ways, do not provide the same level of focus on the medial breast tissue specifically as the ML projection does. The LM (Lateral-Medial) projection also does not target the medial section optimally, as it primarily emphasizes the lateral areas. Therefore, when specifically assessing the medial portion of the breast for lesions, the ML projection is the preferred choice.
