INCREASED MR IMAGE-CONTRAST BY CORRELATION OF TISSUE RELAXATION PROPERTIES

An image postprocessing technique that is based on the relaxation prop erties of tissues and that can produce MR images with increased contra st is proposed. The technique involves no a priori assumptions concern ing the form of the relaxation decay, An arbitrary number of postproce ssed images, each emphasizing a selected tissue type, is obtained from the original images of a multiecho acquisition, It is shown with exam ples that the technique allows more complete utilization of relaxation information for tissue differentiation.
