脑血吸虫病的CT与MRI诊断对比研究

目的：研究脑血吸虫病的CT、MRI表现，并探讨两种检查方法对该病的诊断价值。方法：本组28例患者均同时行CT、MRI检查(平扫 增强)，分析该病的影像学征象并结合9例手术病理资料进行对比。结果：27例有不同程度的水肿；22例呈水肿伴不规则结节，增强后呈结节状、斑片状及融合成簇状强化；CT发现54个病灶．MRI发现75个病灶。结论：脑血吸虫病在CT及MRI增强扫描中都具有特异性表现，MRI信号更接近其病理改变；两种检查方法郜具有重要的临床价值，但MRI明显优于CT。

A comparative study of CT and MRI in the diagnosis of intracerebral schistosomiasis

Objective:To study the CT and MRI findings of cerebral schistosomiasis and assess the value of CT and MRI in the diagnosis of this disease.Methods:28 cases with cerebral schistosomiasis were performed plain and contrast enhanced CT and MRI.The imaging features were analysed.Pathological correlation was studied in 9 cases proved by surgery and pathology.Results:23 cases had different degree edema,22 cases showed edema and irregular nodules,with nodular,spotty or clustered enhancement.54 lesions were found on CT and 75 on MRI.Conclusion:Cerebral schistosomiasis has characteristic appearance on contrast enhanced CT and MRI,and the signal intensity on MRI can demonstrate the pathological changes more accurately.Both methods have important value in diagnosis of cerebral schistosomiasis, and MRI is superior to CT.
