How is the breast positioned during the RM projection?

In the RM (medial-lateral oblique) projection, the breast positioning is critical for obtaining a clear and diagnostic mammogram. In this projection, the inferior surface of the breast is rolled laterally while the superior surface is rolled medially. This positioning allows for better visualization of the breast tissue, including the axillary tail of Spence, and helps minimize superimposition of structures.

Rolling the inferior surface laterally while rolling the superior surface medially ensures that the breast is properly flattened and distributed across the imaging plate. This alignment optimally displays the glandular and fatty tissues, enabling radiologists to detect any abnormalities effectively.

Having the breast positioned in this manner is essential for maximizing the effectiveness of the imaging while adhering to standard radiographic techniques that allow for accurate and thorough examination of the breast.
