Influence of Fat on Liver T-1 Measurements Using Modified Look-Locker Inversion Recovery (MOLLI) Methods at 3T

摘要

Purpose: To characterize the effect of fat on modified Look-Locker inversion recovery (MOLLI) T-1 maps of the liver. The balanced steady-state free precession (bSSFP) sequence causes water and fat signals to have opposite phase when repetition time (TR) = 2.3 msec at 3T. In voxels that contain both fat and water, the MOLLI T-1 measurement is influenced by the choice of TR.
