Fig. 2From: Magnetism of materials: theory and practice in magnetic resonance imagingOpposed-phase (a) and in-phase (b) gradient echo (GE) T1-w. images of the upper abdomen show severe hepatic steatosis. A proton density fat fraction (PDFF) sequence (c) demonstrates a fat fraction of 44% in liver segment VIII. Hydrogen-spectroscopy (d) confirms the fat fraction quantificationBack to article page
