ABSTRACT:
A image is constructed from nuclear magnetic resonance image data which represent a characteristic of an object. Data are collected using the saturation-recovery method and the inversion-recovery method; a first and second image are produced from data from each method, respectively; and a third image is produced from the first and second image, depending only on a single relaxation time.
