DCE-MRIprovides a method to continuously measure the spatial and temporal characteristics of local tissue perfusion. This study points out an interesting feature of DCE-MRI: the voxel wised correlation can be encoded in 26 directions, allowing for the measurement of perfusion tensor. We demonstrate this new method, dynamic perfusion tensor imaging (dPTI), facilitates the reconstruction of the local perfusion field, characterized by a perfusion tensor, from which can be derived quantities related to the structure of the local perfusion field, such as the mean perfusion and perfusion anisotropy.
