[Significance of nuclear magnetic resonance in current diagnosis].

Up to now, a total of 500 patients were examined using a nuclear magnetic resonance imaging system which utilizes a 0.3 Tesla magnet. These data together with others reported in the literature show the possible clinical applications of this technique. Images in 3 projections, high soft-tissue contrast, and different NMR signals lead to outstanding diagnostic visualization of regular tissue and malignant lesions. NMR is currently centred on the central nervous system. Of great importance is its ability to detect lesions in the posterior fossa and in the spinal canal as well as malformations in the cervico-cranial area. The routine use in clinical practice is limited by the lack of standardized imaging parameters and of experience by the examiner himself. But because NMR has the advantages of not being an invasive technique and avoiding radiation or iodine-containing contrast media, patients should, even at this early stage and given a clear indication, not to be deprived of these advantages.
