Which position minimizes the dose to the breast during a mammogram?

The correct answer is the craniocaudal position. This positioning is specifically designed to minimize the radiation dose to the breast tissue during a mammogram. By directing the X-ray beam from the top of the breast downward, this orientation allows for an optimal view of the breast's anatomy while reducing exposure to the glandular tissue.

This technique focuses on compressing the breast from above, optimizing the amount of breast tissue included in the image while effectively minimizing superimposition of structures that could increase radiation exposure. In addition, the craniocaudal view helps in enhancing the clarity of the breast tissue and reducing the background noise in the imaging, which is crucial for effective screening and detection of potential abnormalities.

While other positions, such as the medial-lateral oblique or exaggerated craniocaudal, are also used in mammography, they may not be as effective in dose minimization as the craniocaudal position. Each position can serve specific diagnostic purposes, but the primary goal of minimizing radiation exposure during screening is best achieved with the craniocaudal technique.
