Why should a breast lesion be scanned in radial/ anti radial if found?

Why should a breast lesion be scanned in radial/ anti radial if found?

• A. To visualize tumor or ductal extension branching outward or toward nipple, which could be missed in SAG/TRV
• B. To save time
• C. To reduce radiation exposure
• D. To improve patient comfort

Answer: (A)

The main idea is that the breast’s ducts radiate outward from the nipple, so using planes that follow this natural architecture helps reveal how a lesion extends along those ducts. Scanning in a radial view moves with the nipple-ward pattern, allowing you to trace whether the tumor reaches or involves the subareolar ducts or extends toward the nipple itself. The anti-radial view provides a perpendicular perspective to confirm the extent and catch extensions that might run in a different direction. In contrast, standard sagittal or transverse views can cut across the ducts and potentially miss subtle ductal spread, leading to underestimation of the lesion’s reach. This precise mapping of ductal involvement informs surgical planning and management. Radiation exposure and patient comfort aren’t the primary reasons for choosing radial/anti-radial planes, and ultrasound itself doesn’t involve ionizing radiation, so those considerations aren’t the driving factor here.
