MRS could be useful for characterization of the renal cell carcinoma by detecting lipid content. However, single-voxel MRS cannot show the distribution of lipids for heterogeneous tumors. We propose a fast MRSI sequence to map the distribution of lipid metabolites within a clinically acceptable time frame at 3T. The proposed MRSI technique provided high-quality data with reproducible quantitative outputs. The coefficient of variance for the quantified fat fraction was less than 1%.
