The application of magnetic resonance imaging in maxillo-facial region: A comparison with CT

摘要

Magnetic resonance imaging (MRI) studies were obtained in 49 cases of various diseases in the maxillo-facial region and the results compared with X-ray computed tomography (CT). Bot MRI and CT scans were performed in 44 cases. In 31 cases (70), MRI provided similar or superior information to that of CT in the evaluation of various diseases. In 10 cases, MRI was superior to CT in defining the images of diseases, 7 cases of these were carcinomas. CT was superior to MRI in 5 cases, especially in demonstrating calcifications and bony changes. Artifacts caused by prosthetic metals and patient motion disturbed MR images. Our experience with MRI lead us the conclusion that it holds great potential and that it already had some advantages over CT in the maxillo-facial region.
