Abstract

The quantification of intrahepatic lipids (IHLs) has attracted a great deal of interest pertaining to diagnostic treatment of type 2 diabetes mellitus. We report on an innovative approach to visualizing IHLs quantitatively by creating the best mix of the advantages of proton magnetic resonance spectroscopy (MRS) and the gradient echo (GRE) sequence on a 1.5T MR system. Proton MRS is considered to have the best precision and reliability; however, measuring a single voxel is time-consuming. On the other hand, the GRE sequence can provide information on IHLs, at least not quantitative, in a very short time. IHL images can be created from the correlation between the relative content of IHLs obtained with proton MRS and the signal intensity of GRE images with a very high correlation coefficient (R=0.992). Our approach holds great potential for quantifying fat accumulation in every possible tissue quickly and precisely.
