Common questions
What does Liver LI-RADS (CT/MRI HCC) Category do?
Categorise an observation on diagnostic CT/MRI in patients at high risk for HCC.
How is the result calculated?
Major features — non-rim APHE, size, non-peripheral washout, enhancing capsule, threshold growth (≥ 50%/≤ 6 mo) — combine to LR-3/4/5. 10–19 mm + APHE + washout or threshold growth = LR-5.
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
