Liver protocol (MRI)

Examination of the liver with MRI requires numerous sequences and imaging at multiple times after the administration of gadolinium. Many variations exist, but a typical protocol would include: 

Pre-contrast
  • T2
  • T2 fat sat
  • T1 weighted gradient echo in and out of phase
  • T1 2D or 3D gradient echo equences (e.g. VIBE)
Post-contrast
  • T1 2D or 3D gradient echo equences (e.g. VIBE) at
    • arterial phase: 20-25 seconds
    • portal venous phase: 60-70 seconds
    • equilibrium phase: 3-5 minutes
    • hepatobiliary delayed phase: 10-30 minutes with and without fat sat
    • later delayed phase: 1 hour +/- 3 hours in some institutions
