CONTRAST-ENHANCED MRI OF THE LIVER — LI-RADS v2018 TECHNIQUE: Multiphase MRI with Extracellular agent (ECA). CLINICAL CONTEXT: LI-RADS applicable high-risk context assumed (specify cirrhosis, chronic HBV, or current/prior HCC). COMPARISON: None available. FINDINGS: Liver observations: 1. Observation 1 (Not specified): Incomplete input — select APHE and enter size to categorize. IMPRESSION: No categorizable LI-RADS observation. Correlate with clinical findings and complete the observation inputs.
LI-RADS CT/MRI v2018 — diagnostic categories
HCC probability and management by ACR CT/MRI LI-RADS v2018 category. Mirrors the categories assigned by the calculator above.
| Category | HCC probability | Typical management |
|---|---|---|
| LR-1 | Definitely benign | Return to routine surveillance (e.g., 6-month imaging). |
| LR-2 | Probably benign | Surveillance imaging, generally in 6 months. |
| LR-3 | Intermediate probability of malignancy | Repeat or alternative diagnostic imaging in 3–6 months. |
| LR-4 | Probably HCC | Multidisciplinary discussion; consider biopsy or repeat/alternative imaging. |
| LR-5 | Definitely HCC | Biopsy not required; multidisciplinary management. |
| LR-M | Probably/definitely malignant, not HCC-specific | Multidisciplinary discussion; biopsy usually required. |
| LR-TIV | Definite tumor in vein | Multidisciplinary discussion; treat as malignant. |
| LR-NC | Cannot be categorized | Repeat or alternative imaging, generally within 3 months. |
Key decision rules (CT/MRI v2018)
- LI-RADS v2018 applies only to patients at high risk for HCC (cirrhosis, chronic HBV, or current/prior HCC); it is not used in the general population.
- The diagnostic table combines the major features — nonrim APHE, nonperipheral washout, enhancing capsule, and threshold growth — with observation size to assign LR-3 through LR-5.
- LR-M is assigned for targetoid or rim-APHE features that favor a malignancy other than HCC, and takes precedence over the diagnostic table.
- LR-TIV indicates definite tumor in vein (enhancing soft tissue within a vessel).
- LR-NC is assigned when the study cannot be categorized because of image omission or degradation.
- Ancillary features can adjust the category by up to one step (up for malignancy, down for benignity) but cannot raise an observation to LR-5.
