(MPR) The postprocessing reformatting of a 3D data set into 2D slices of arbitrary thickness at any angle. For a good resolution thin slices, isotropic voxel and overcontiguous slices (overlapping slices) for good signal are advantageous.
MR imaging technique in which a set of projection profiles of the body is obtained by observing MR signals in the presence of a suitable corresponding set of magnetic field gradients. Images can then be reconstructed using techniques analogous to those used in conventional computed tomography (CT), such as filtered back projection. It can be used for volume imaging or, with plane selection techniques, for sequential plane imaging.
