Which annotations are acceptable for documenting breast ultrasound findings?

• A. Quadrant method
• B. Clock method
• C. 123 method (distance from nipple projection line)
• D. Quadrant method, clock method, 123 method, and ABC method

Answer: (D)

Consistent localization of a breast lesion on ultrasound is essential for accurate documentation, follow-up, and surgical planning. There are several accepted ways to annotate where a finding lies, and all are valid as long as the description is clear and reproducible. The quadrant method uses the four breast regions defined around the nipple, allowing quick reference to roughly where a lesion is located. The clock method treats the breast like a clock face with the nipple as the center, so positions are described like “2 o’clock.” The 123 method provides a precise coordinate by giving distances from a nipple projection line, which helps pinpoint small or subtly located findings. The ABC method is another commonly used labeling system in practice, offering an alternative reference framework that some teams prefer for consistency with prior studies or surgical planning. Because each method relies on consistent landmarks and provides clear spatial information, they are all acceptable. The key is to use a chosen system consistently and include measurements or descriptors that make the location unambiguous for radiologists, surgeons, and other clinicians.
