Abstract
NMR images were obtained in 12 patients with mass lesions in the posterior fossa and the results compared with X-ray computed tomography (CT). Inversion recovery T1-weighted images demonstrated abnormalities in 6 of 6 intrinsic lesions and 3 of 6 extrinsic lesions. Spin echo T2-weighted images demonstrated abnormalities in 2 of 2 intrinsic lesions and 4 of 5 extrinsic lesions. Saturation recovery T1-weighted images were normal in 2 of 2 intrinsic lesions and 2 of 4 extrinsic lesions. Overall, NMR detected 11 of 12 lesions. Two intrinsic tumors detected by NMR were not detected by CT evaluation. Two small extrinsic tumors required CT gas cisternogrpahy for detection.Keywords
