title: In vivo tumor discrimination in a rat by proton nuclear magnetic resonance imaging.
abstract: Transverse cross-sectional images which represent the spatial distribution of the proton nuclear magnetic resonance signal in a live Wistar rat have been produced by the multiple-sensitive-point method. The images form a chronological series demonstrating the detection and development of a D23 hepatoma in the abdomen. Discrimination of the tumor is by contrast with the surrounding tissue and is attributed to the elevated water content and relaxation times of the  former.
