Abstract

After it was discovered that malignant tissue has a higher T1 than normal tissue (Damadian 1971), much emphasis was placed on the determination of relaxation parameters in the hope that these parameters might identify different tissues or the same tissue in different pathological states. It is now generally accepted that it is not possible to differentiate between normal, benign, and malignant tissues using only one of the relaxation parameters. The simultaneous use of additional parameters determined by multiecho MR imaging, and the model-based generation of new images, can, however, provide better characterization of different tissue types.
