| 摘 要： | 目的：探讨CT及MRI对结节性硬化的诊断价值。方法：回顾分析经临床病理证实的32例结节性硬化（TS）的CT、MRI资料。结果：CT表现为脑室周围的结节状钙化，脑实质错构瘤，室管膜下巨细胞星形细胞瘤。MRI表现为脑实质多发异常信号灶，T1WI呈低信号，T2WI呈高信号。结论：结节性硬化的CT表现有一定特征性，对临床疑TS的患者，CT检查很有必要。MRI检查能发现更多病变，对非钙化性病变比较敏感，两者起互补作用。

| Abstract: | Objective:This study was set to understand the value of CT and MRI on the diagnosis of tuberous sclerosis.Methods:Retrospectic analysis of 32 cases of tuberous sclerosis which were justified by clinical and pathology.Results:Typical periventricular nodules calcified that projected into the lateral ventricles were found on CT.Parenchymal hamartomas and subependymal giant cell astrocytomas (SGCA) were also foud.Multiple parenchymal abnormal signal were displayed on MRI T 1 weighted image show relatively decreased signal intensity,and T 2 weighted image show relatively increased signal intensity of lesion.Conclusion:Special manifestation on CT were helpful to diagnosis tuberous sclerosis,our reseach suggest that it is necessary to take CT examinations to relevant case.By contrast,MRI is more sensitive in lesions,esp to noncalcified cases.The function of MRI and CT were complementarily. |
