The radial orientation is described as being parallel to what structure?

The radial orientation is described as being parallel to what structure?

• A. The ducts
• B. The skin
• C. The chest wall
• D. The nipple

Answer: (A)

Radial orientation in breast imaging follows the path of the ducts that radiate outward from the nipple. These ducts extend from the nipple toward the outer breast, so a line described as radial is aligned parallel to that ductal pattern. The skin sits on the surface, the chest wall lies deeper and at a different alignment, and the nipple is the origin point of the ducts rather than a structure to be parallel to.
