Intravoxel incoherent motion modeling in the kidneys: Comparison of mono‐, bi‐, and triexponential fit
PURPOSE To evaluate if a three-component model correctly describes the diffusion signal in the kidney and whether it can provide complementary anatomical or physiological information about the underlying tissue. MATERIALS AND METHODS Ten healthy volunteers were examined at 3T, with T2 -weighted imaging, diffusion tensor imaging (DTI), and intravoxel incoherent motion (IVIM). Diffusion tensor ...
متن کاملImproved Robustness with a Stretched Exponential Model for Intravoxel Incoherent Motion (IVIM) DW Signal
INTRODUCTION Le Bihan et al (1) proposed using diffusion-weighted imaging (DWI) based on intravoxel incoherent motion (IVIM) to distinguish pure molecular diffusion and microcirculation, or blood perfusion, by acquiring DW data with the diffusion sensitivity parameter b at low values (<200 sec/mm and at high values (>200 s/mm). The ability of IVIM to provide sensitive and specific values for th...
متن کاملUtility of intravoxel incoherent motion diffusion-weighted imaging in differentiating renal cell carcinoma from angiomyolipoma
We discussed the utility of intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) for discriminating clear cell renal cell carcinoma (ccRCC) from angiomyolipoma (AML). Preoperative IVIM-DWI parameter (ADC,D, D and f) values were compared between the ccRCC (n = 37) and AML (n = 28) groups. AML exhibited significantly lower ADC ([1.35±0.29] × 10-3 mm2/s vs [1.77 ± 0.41] × 10-3 mm2/s)...
