Anti radial is considered to be which orientation relative to the ducts?

• A. Perpendicular/ TRV to the ducts
• B. Parallel to the ducts
• C. Along the chest wall
• D. Diagonal to the nipple

Answer: (A)

Anti-radial orientation means a line that is at right angles to the ducts. The ducts radiate outward from the nipple like spokes on a wheel, so a direction along the ducts is radial, while anti-radial is perpendicular to them. In practice this corresponds to a transverse (TRV) view across the ducts, giving a cross-sectional perspective of the ductal area and surrounding tissue. This is why the best choice is perpendicular to the ducts. Lines parallel to the ducts would align with them (radial), and orientations along the chest wall or diagonal to the nipple don’t specifically describe the relationship to the ducts.
