Initial experience with nuclear magnetic resonance (NMR) imaging of the human breast.

Two patients with breast abnormalities, one malignant and one benign, were studied with nuclear magnetic resonance (NMR) imaging utilizing a cryogenic superconducting magnet. Three-dimensional NMR images were obtained in one case and single slice planar images were obtained in the other. The NMR images correlated well with the corresponding mammograms. Although both conditions exhibited a different signal intensity for the area of abnormality compared to adjacent ductal and fatty tissue, the configuration of the abnormal areas allowed distinction between benign and malignant process.
