Increased MR image contrast by correlation of tissue relaxation properties.
An image postprocessing technique that is based on the relaxation properties of tissues and that can produce MR images with increased contrast is proposed. The technique involves no a priori assumptions concerning the form of the relaxation decay. An arbitrary number of postprocessed images, each emphasizing a selected tissue type, is obtained from the original images of a multiecho acquisition. It is shown with examples that the technique allows more complete utilization of relaxation information for tissue differentiation.
