In mammography, how should the central ray be positioned for the mediolateral oblique projection?

Parallel to the base of the breast
Perpendicular to the base of the breast
Angled 30 degrees
Angled 60 degrees

The correct answer is: Perpendicular to the base of the breast

For the mediolateral oblique projection in mammography, positioning the central ray perpendicular to the base of the breast is crucial to ensure optimal imaging. This angle helps to capture the maximum amount of breast tissue in the image without distortion, which is essential for accurate diagnosis. In this projection, the breast is positioned at an angle to the detector, allowing for better visualization of the upper outer quadrant of the breast where a significant number of breast abnormalities can occur. When the central ray is perpendicular to the detector, it allows for clearer visualization of potential lesions and reduces the chances of superimposing other structures over the area of interest. Maintaining this perpendicular alignment also helps in minimizing magnification and distortion, which is particularly important for identifying microcalcifications and assessing masses. By adhering to this positioning standard, the quality of the mammography images is enhanced, leading to more accurate interpretations. Overall, the correct central ray positioning aligns with the established protocols in mammography aimed at improving diagnostic efficacy.
