LI-RADS (Liver Imaging Reporting and Data System)

When it activates

Scribeable activates a calculator from the encounter. The LI-RADS (Liver Imaging Reporting and Data System) can activate when the transcript or pasted chart context documents any of these:

• Liver lesion characterization
• HCC screening interpretation
• Liver MRI or CT assessment
• Hepatocellular carcinoma diagnosis
• Liver transplant listing evaluation

Inputs the note needs

1 input. Each is resolved from the transcript, the pasted chart context and charted labs; at this calculator’s tier a missing input is never requested, and a missing required input keeps the score out of the draft.

Scoring

LR-1: Definitely benign. LR-2: Probably benign. LR-3: Intermediate probability of malignancy. LR-4: Probably HCC. LR-5: Definitely HCC. LR-M: Probably or definitely malignant, not HCC-specific. LR-TIV: Tumor in vein (definite). Based on arterial phase hyperenhancement, observation size, washout, capsule, and threshold growth.

Interpretation

LR-1/2: Continue surveillance per protocol. LR-3: Repeat diagnostic imaging in 3-6 months (may also biopsy). LR-4: Probable HCC — multidisciplinary discussion, biopsy or treat. LR-5: Definite HCC diagnosis (no biopsy needed per AASLD) — proceed to staging and treatment. LR-M: Non-HCC malignancy possible (cholangiocarcinoma, combined tumors) — biopsy recommended. LR-TIV: Tumor in vein — advanced disease, impacts transplant eligibility. LR-5 and LR-TIV confer UNOS automatic MELD exception for transplant.

How Scribeable handles it in the note

When an encounter activates the LI-RADS (Liver Imaging Reporting and Data System) (its highest tier is recommended), Scribeable does not ask you for missing inputs. The score is computed in code from whatever inputs resolve from the transcript, the pasted chart context or charted labs; a computed value is written into the draft only when every required input already resolves.

The score is computed in code from the resolved inputs, not recalled by the language model. A stated LI-RADS (Liver Imaging Reporting and Data System) value is compared against the computed one when the draft's structured summary carries it; a disagreement found there is flagged to the second drafting pass, which is instructed to correct the score and its interpretation, unless Scribeable has supplied the computed value to that pass, in which case the value the draft writes is checked against the supplied one and a detected difference is shown beside the note for you to adjudicate rather than silently rewritten.

Classified as a staging or classification system: activated strictly, because a wrong stage on the wrong patient is a documentation hazard.
