Popis: Thirteen patients with nasal and paranasal sinus diseases were examined with nuclear magnetic resonance computed tomography (NMR-CT).1. The NMR appearance of the pathological features in the paranasal sinuses was much clearer than the X-ray CT appearance because there were no image artifacts due to bone and air.2. Mucosal pathology and the quality of secretions in the sinuses could be demonstrated by measuring hydrogen proton density and the T1 value.3. NMR is a useful tool in deciding further investigations and operative approaches because tumor invasion can be analyzed three dimensionally.4. Bone destruction and calcification cannot be visualized by NMR, since no signals from bone are recorded in this process.
