Renal Adiposity Confounds Quantitative Assessment of Markers of Renal Diffusion With MRI A Proposed Correction Method

摘要

Objectives: Recent studies have indicated that excessive fat may confound assessment of diffusion in organs with high fat content, such as the liver and breast. However, the extent of this effect in the kidney, which is not considered a major fat deposition site, remains unclear. This study tested the hypothesis that renal fat may impact diffusion-weighted imaging (DWI) parameters, and proposes a 3-compartment model (TCM) to circumvent this effect.
