Overview
Abdominal MRI uses multiphase contrast enhanced imaging combined with diffusion and T2 sequences for lesion detection and characterization.
Core Sequences
Include T2 weighted single shot and fat suppressed sequences diffusion weighted imaging and dynamic contrast enhanced T1 weighted phases arterial portal and delayed.
Liver Specific Additions
Add hepatobiliary contrast agents and hepatocyte phase imaging for focal nodular hyperplasia and small lesion detection when indicated.
Patient Preparation
Fasting and antiperistaltic agents reduce motion and improve lesion conspicuity; tailor breath hold instructions to patient ability.
