If a breast lesion is found, the area should be scanned in which orientation?

If a breast lesion is found, the area should be scanned in which orientation?

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

Answer: (A)

In breast ultrasound, evaluating a found lesion in radial and anti-radial orientations best reflects the natural ductal anatomy of the breast. The radial view lines up with the axis of the ducts that radiate from the nipple, letting you trace the lesion around the clock and accurately see its true shape and margins as they extend along or around those ducts. The complementary anti-radial view provides a perpendicular perspective, helping to reveal any irregularities, extensions, or parts of the lesion that might be hidden in a single plane. Relying on just one orientation can miss aspects of the lesion or misjudge its extent, whereas scanning in both radial and anti-radial directions gives the most complete characterization of size, margins, and relationship to the ductal system.
