About this tool (heuristics & limitations)

This single-file page helps you summarize ultrasound features and generates copy-ready report text. It also provides an educational subtype tendency estimate using a simple scoring rubric derived from commonly reported feature–subtype associations. It is not validated and must not be used for clinical decision-making.

  • Triple-negative (TNBC): more often oval/round, circumscribed, posterior enhancement, complex cystic/solid, low–moderate stiffness, peripheral/rim vascularity.
  • HER2-enriched: more frequent microcalcifications, irregular or heterogeneous appearance, marked internal vascularity, edema/ductal changes, sometimes enhancement.
  • Luminal A: irregular/spiculated, posterior shadowing, less vascular, often stiffer, smaller size.
  • Luminal B: overlaps with Luminal A but tends to be more aggressive features (non-parallel, calcifications, indistinct/angular margins, higher vascularity).
