    摘要: Systems and methods for imaging and quantifying tissue magnetism with magnetic resonance imaging (MRI) are disclosed. According to an aspect, a method for MRI includes using an MRI system to acquire multiple image echoes of an object. The method also includes combining the image echoes. Further, the method includes generating an image of the object based on the combined image echoes for depicting a characteristic of the object.

    摘要: Systems and methods for susceptibility tensor imaging in the p-space are disclosed. An example method includes using an MRI system to generate an MRI signal of an object. The method may also include conducting a multipole analysis of the MRI signal in a subvoxel Fourier spectral space (p-space). Further, the method may include sampling the p-space with pulsed field gradients to determine a set of dipole and quadrupole susceptibility tensors. The method may also include generating an image of the object based on the set of dipole and quadrupole susceptibility tensors for depicting a characteristic of the object.
