摘 要: | 为了解骶管脊膜囊肿(SMC)在MR脊髓成像上的表现及评价MR脊髓成像对SMC的诊断价值,作者研究10例病人,主诉后下背痛(5例)、单侧腿疼(4例)和腹痛(1例)。SMC的诊断由手术和MRI做出(各5例)。后者随后行手术被确诊为硬膜外脊膜囊肿。磁共振扫描仪为0.5T(9例)和1.5T(1例)。MR平扫包括自旋回波矢状位T_2WI(4000/120/2~4/5mm[TR/TE/NSA/层厚]),T_1WI(400~500/12~30/1~2/5mm)及横断位T_1WI(500~600/15~20/1~2/5~6mm)。MR脊髓成像分别选用2D和3D single-shot快速自旋回波扫描序列。2D MR脊
