Planning

Choice of modality

For the liver, the initial imaging of choice is generally as follows:

Technique

Requires a phased array torso coil.

Basic screening

  • Morphology: verify size, borders and contours.
  • Liver parenchyma: Scan for steatosis, iron deposition
  • Focal lesions: Scan for nodules
  • Biliary ducts:
  • Hepatic veins
  • Portal vein

Search for extrahepatic findings

  • Lymph nodes in hepatic hilum.
  • Signs of portal hypertension: ascites, splenomegaly; portosystemic collateral vessels

Report

LI-RADS (Liver Imaging and Reporting Data System) system should be used only if patient has a high risk for hepatocellular carcinoma (cirrhosis, chronic hepatitis B or current/prior HCC).
