The proposed method is based on the perfusion model of intravoxel incoherent motion (IVIM), which assumes that perfusion is a microcirculation of blood in the capillary network. The method introduces two-types of bi-polar gradients in a radial spin-echo sequence, a new ordering of bi-polar gradients for isotropic perfusion weighting, and signal models for quantitative analysis of perfusion. To verify the proposed method, in-vivo imaging in 3 T MRI was performed, and the proposed method offers the high-resolution quantitative perfusion map.
