Stretched-exponential model enables diffusion analysis considering diffusion varieties in each voxel on abdominal DWI. Our study showed stretched-exponential model has a potential to increase diagnostic performance of pancreatic DWI. Alpha has a potential to be used for malignant lesion differentiation.
