MRI of the liver in cases active desease

( MRI of liver )Axial liver breath-hold images of an intra-hepatic FNH, in the setting of a diffusely abnormal liver with features of steatohepatitis on fat-suppressed single-shot T2-weighted.

If this component of the gadolinium-enhanced tissue perfusion was not included, or incorrectly timed, the abnormal liver enhancement of hepatitis and the arterial phase-dominant characteristics of the FNH would not be recognized, as these are transient features.
