摘要
目的：评价ＧｄＤＴＰＡ增强磁共振成像对脑囊虫病的诊断价值。方法：经血清免疫学检查或手术病理证实的４４例脑囊虫病患者行磁共振成像检查，成像序列为：ＳａｇＳＥＴ１ＷＩ、ＡｘｌＳＥＴ１ＷＩ、Ｔ２ＷＩ及Ｔ１ＷＩ＋Ｃ（Ｓａｇ，Ａｘｌ或Ｃｏｒ）。总结各序列图像对脑囊虫病病例、病灶、病灶数目、发病部位、灶周水肿及头节的显示率。结果：Ｔ１ＷＩ、Ｔ２ＷＩ及Ｔ１ＷＩ＋Ｃ对病变的显示率分别：７４％、９１％、１００％；头节的显示率分别为３４％、７％、３８％；灶周水肿的显示率分别为２１％、４３％及２４％，且Ｔ１ＷＩ＋Ｃ较Ｔ２ＷＩ检出病灶数目高出５０％。囊肿的形态、囊壁的厚薄较Ｔ１ＷＩ显示更清晰。结论：ＧｄＤＴＰＡ增强ＭＲＩ对脑囊虫病的检出，定性诊断及分期帮助很大，对头节的显示与Ｔ１ＷＩ相似，显示灶周水肿较Ｔ２ＷＩ差。ＧｄＤＴＰＡ增强在脑囊虫病的诊断中应列为常规序列。
Purpose:To evaluate the value of gadolinium enhanced MRI in the diagnosis of cerebral cysticercosis.Methods:44 cases of cysticercosis proved by serum immunoassay or pathology were studied.Scanning methods include Sag SE T 1WI,Axl SE T 1WI、T 2WI and T 1WI+C. Sum up the rate of lesion detecting.Results:The rate of demonstration of lesions in T 1WI、T 2WI and T 1WI+C were 74%, 91% and 100%;the scolex detection rate was 34%,7% and 38%; and that of perifocal edema were 24%,43% and 24% respectively.The lesions detected by T 1WI+C were 50% more than that found by T 2WI,but the shape and thickness of wall of cysticercosis were more clear in T 2WI.Conclusion:Gadolinium enhanced MRI plays an important role in the diagnosis of the cerebral cysticercosis.
