Abstract

Nuclear magnetic resonance (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 six of six intrinsic lesions and three of six extrinsic lesions. Spin echo T2-weighted images demonstrated abnormalities in two of two intrinsic lesions and four of five extrinsic lesions. Saturation recovery T1-weighted images were normal in two of two intrinsic lesions and two of four 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 cisternography for detection.

摘要

对12例后颅窝有占位性病变的患者进行了核磁共振（NMR）成像检查，并将结果与X线计算机断层扫描（CT）进行比较。反转恢复T1加权像显示，6例原发性病变中的6例及6例继发性病变中的3例有异常。自旋回波T2加权像显示，2例原发性病变中的2例及5例继发性病变中的4例有异常。饱和恢复T1加权像显示，2例原发性病变中的2例及4例继发性病变中的2例正常。总体而言，NMR检测出了12个病变中的11个。NMR检测出的2例原发性肿瘤CT检查未发现。2例小的继发性肿瘤需行CT脑池造影才能检测出。
