[Nuclear resonance tomography of the breast--diagnosis, differential diagnosis, problems and solutions. I. Study procedures].

The experience gained from performing nuclear resonance tomography on the breast, using a special surface coil, is described. The technical problems, causes of artefacts and the advantages of tomography in three planes are discussed. The procedure is slow. Images obtained by various repetition and echo delay times in several planes are illustrated. Problems in quantifying T1 and T2 images and methods for improving the technique are described in detail. During the course of 85 examinations on 72 patients, it has been possible to achieve technical improvements.
