Why does radial scanning best demonstrate a papilloma?

• A. It best examines lobular architecture
• B. It best examines ductal structures
• C. It provides better bone visualization
• D. It shows vascularity best

Answer: (B)

Radial scanning is ideal for mapping the ductal system around the nipple. Papillomas are intraductal lesions that grow inside the lactiferous ducts and often present as a small intraluminal mass or cause dilation of the ducts just beneath the areola. By tracing the ducts in a circular, clock-face view around the nipple, you can directly follow the ductal pathways and visualize any intraductal mass and its relationship to the duct lumen. This makes ductal structures the key feature to assess for a papilloma.

Other aspects like lobular architecture or bone appearance aren’t the primary clues for this lesion, and while vascularity can indicate a solid lesion, it’s not the defining factor for identifying a papilloma.
