The recommended scanning approach to assess ductal extension after lesion detection is:

• A. Radial/anti radial
• B. Sagittal only
• C. Transverse only
• D. Coronal only

Answer: (A)

Evaluating how far a lesion extends along the ductal system is best done with radial and anti-radial ultrasound views because these planes trace the ducts as they radiate from the nipple. Ducts branch out in multiple directions, so mapping them in radial angles around the nipple provides a comprehensive 360-degree view of how the lesion may be involved along the ductal tree. The anti-radial orientation complements this by looking at perpendicular angles, helping to confirm and extend the assessment across the ducts. Relying on a single plane—whether sagittal, transverse, or coronal—can miss extensions that lie off that plane, since one view cannot capture the entire three-dimensional ductal network. Using radial and anti-radial views yields the most accurate picture of ductal extension, guiding accurate sizing and surgical planning.
