Nuclear magnetic resonance (NMR) imaging in diseases of the central nervous system: initial results.

Initial experiences with Nuclear Magnetic Resonance (NMR) imaging in various intracranial diseases are reported. The images were obtained with a 0.2 Tesla resistive magnet NMR-imager of SIEMENS and the influence of different imaging techniques (spin-echo and inversion recovery) with various imaging parameters (spin-echo) on the quality and the character of the images were studied. Typical clinical examples are demonstrated and first comments are made on the quantitative evaluation of T1- and T2-relaxation times.
