The NMR-Tomography as a new imaging device is still in the experimental stage for clinical use. It has distinct advantages in comparison to other conventional methods especially when considering special indications and clinical considerations. In some cases NMR-Tomography can only be carried out when a patient is under general anesthesia. This anesthesia must be performed in accordance with the basic nature of this imaging method, i.e. one always has to remember that no ferromagnetic material can be used in the vicinity of the apparatus. With our described method a certain and safe performance of general anesthesia for NMR-Tomography is possible.
