Improved intravoxel incoherent motion analysis of diffusion weighted imaging by data driven Bayesian modeling

In addition to the diffusion coefficient, fitting the intravoxel incoherent motion model to multiple b‐value diffusion‐weighted MR data gives pseudo‐diffusion measures associated with rapid signal attenuation at low b‐values that are of use in the assessment of a number of pathologies. When summary measures are required, such as the average parameter for a region of interest, least‐squares based methods give adequate estimation accuracy....
