22 patients were imaged using a chemical-shift encoded
water-fat MRI sequence (IDEAL-IQ) on 1.5T with a low
flip angle (8 degrees), before and after administration
of a conventional gadolinium-based contrast agent.
Hepatic fat fraction (HFF) was measured by drawing 5
ROIs per liver on pre-gadolinium images, which were
copied to matching locations of the post-gadolinium
images. Results: HFF values were not significantly
influenced by administration of gadolinium. This allows
for examination time reduction by performing the HFF
acquisition in the interval between dynamic and delayed
phase imaging post-gadolinium.
