Abstract

Objective To investigate the MRI chemical shift imaging of the mild fatty liver. Methods To explore the imaging characteristics of MRI chemical shift among 35 cases of normal liver and mild fatty liver. MRI sequence of T1WI phase (in-phase), T1WI reverse phase (out-phase). Results The T1WI in phase signal of 35 cases of normal liver were basic signal, the T1WI out phase showed high signal. The T1WI in phase signal of 35 cases of mild fatty liver were equisignal, 21 cases showed equal T1WI reverse phase signal, 14 cases showed slightly higher signal. Conclusion When Liver out-phase signal is equal to or slightly higher than the in-phase signal, it should be considered mild fatty liver.
