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:
- T2 fat sat
- T1 weighted gradient echo in and out of phase
- T1 2D or 3D gradient echo equences (e.g. VIBE)
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
