What is the proper annotation for quadrant levels of the right breast?

• A. UIQ, LIQ, LOQ, UOQ
• B. RUQ, LUQ, LOQ, UOQ
• C. UIQ, RUQ, LOQ, UOQ
• D. UIQ, LIQ, RQ, UOQ

Answer: (A)

In breast imaging, location is described using the four quadrants around the nipple: upper inner, upper outer, lower inner, and lower outer. For the right breast, you simply use those quadrant names without adding side prefixes. So the proper annotation is UIQ, UOQ, LIQ, and LOQ—the four standard quadrant labels. Using right- or left-prefixed terms (like RUQ or LUQ) or an nonstandard abbreviation like RQ would mix sides or introduce an nonstandard label, which isn’t how a single breast’s quadrants are described.
