Tumor perfusion‐related parameter of diffusion‐weighted magnetic resonance imaging: Correlation with histological microvessel density

Purpose We obtained intravoxel incoherent motion (IVIM) parameters through biexponential analysis on diffusion‐weighted MR imaging (DWI) using multiple b values. Correlation was evaluated between these parameters and histological microvessel density (MVD) for the possibility of noninvasive evaluation of MVD with DWI. Methods Twenty‐five nude mice with the HT29 colorectal cancer cells implanted were analyzed after undergoing DWI with multiple b...
