摘要: 目的:探讨CT与MRI在松果体囊肿诊断中的价值.材料与方法:5例病例均做CT检查3例同时做CT与MRI检查,其中2例行CT与MRI增强检查结合文献资料加以分析和总结.结果:CT扫描5例囊肿均位于松果体区,呈类圆形低密度区,边界光滑锐利CT值为12-16HuMRI在T1加权橡上呈低信号,T2加权像表现为高信号,与脑脊液信号相仿.结论CT和MRI对松果体囊肿的诊断有重要作用,为其临床诊断与治疗提供有力的证据.Abstract: Objective: To evaluate the value of CT and MRI in the diagnosis of conariumcysts. Materials and Methods:Five Patients with conarium cysts were studied by CT,3 of them were studied by MRI and CT,2 of them were taken by enhanced MRI and CT examnations.And reviewed some aboutliteratures. Results:All the patients showed rounded systic conarium which were well delineatedCT scans of five cases revealed rouned liquid-density lesions in the conarium regions respectively.The lesionswere well defined and the CT values were 12-16Hu;The lesions were hypointensity on T1-Weighted spin-echopulse sequences and hyperintheity on T2-Weighted images of MRI. Conclusions:Conarium cysts and theircharacteristic manifestations could be well demonstrated on CT and MRI.
