When to use
Hepatobiliary MRI is superior to CT for focal liver lesion characterization (especially in cirrhotic liver — LI-RADS), biliary tree assessment (MRCP), chronic pancreatitis, Crohn's disease (MR enterography) and deep endometriosis.
What to evaluate
- Focal liver lesions: T1/T2 signal, diffusion, dynamic enhancement pattern, hepatobiliary phase (with Primovist).
- Biliary tree: caliber, filling defects, congenital anomalies.
- Pancreas: main duct, focal lesions, calcifications.
- Quantification: liver fat (PDFF), liver iron (R2*) when applicable.
- Bowel (MR enterography): thickening, enhancement, inflammatory signs, fistulae.

Frequently asked
- LI-RADS — when to use Primovist (gadoxetate)?
- Hepatobiliary agent with specific hepatobiliary phase (20 min post-injection) helps characterize HCC, FNH and metastasis. Advantages in LR-3 and LR-4 with borderline washout features.
- When MRI in pancreatitis?
- Recurrent pancreatitis without clear etiology (MRCP for microlithiasis, congenital anomalies), chronic pancreatitis for duct mapping and cystic lesion characterization.
- Liver fat quantification — which technique?
- PDFF (proton density fat fraction) with multi-echo sequences is the non-invasive reference. > 5% indicates steatosis; correlate with biopsy in clinical studies.
