When to use

Structured assistance in assigning a breast-ultrasound BI-RADS category from descriptors.

How it works

Simple-cyst pattern → 2; all benign-leaning features → 3; any suspicious feature (irregular shape, not parallel, non-circumscribed margin, complex, posterior shadowing, suspicious calcifications, associated features) → 4–5 by number/severity.

Key points

  • BI-RADS has no official point algorithm — the category is set by the most suspicious feature.
  • Spiculation or skin/nipple retraction lean toward category 5.
  • A simple-cyst pattern (anechoic, circumscribed, posterior enhancement) is category 2.
  • The 4A/4B/4C sub-division is the physician's integrated malignancy estimate.
