| 摘 要： | 目的探讨磁共振(MR)扩散加权成像(DWI)和增强磁共振对颅内囊性病变的诊断价值。方法应用1.5TMR对20例脑脓肿、26例胶质瘤、29例转移瘤、14例表皮样囊肿、26例蛛网膜囊肿进行常规MR、DWI成像、表观扩散系数(ADC)测量和增强MR检查,分析其影像学表现。结果脑脓肿、胶质瘤和转移瘤全部强化,表现为环状或花环状强化;表皮样囊肿、蛛网膜囊肿病例不强化。DWI上16例脑脓肿和14例表皮样囊肿呈高信号;26例蛛网膜囊肿均为低信号;55例脑肿瘤患者中,5例胶质瘤呈高信号,13例呈混杂信号,其中10例为胶质瘤,3例转移瘤,其余均为低信号。结论 MR扩散加权成像及增强磁共振在颅内囊性病变的定性诊断中具有重要价值。 |
