| 摘 要： | 目的探讨脑室内积脓的MRI表现。方法回顾性分析经临床证实的5例脑室内积脓病人的MRI表现。所有病人做了MRI平扫,3例做了扩散加权成像。结果5例病人都表现为双侧侧脑室承重部位的组织碎屑、脓液-脑脊液平面,脓液在T1WI呈相对于脑脊液的稍高信号,T2WI呈相对于脑脊液的稍低信号。1例在扩散加权像为高信号,2例为等信号。结论脑室内积脓的MRI表现具有特殊性,能够明确诊断。

| Abstract: | Objective To analyze the MR imaging features of pyocephalus. Methods MR imaging features!of pyocephalus in 5 cases with clinically proved were analyzed retrospectively. All patients were undergone no-contrast MR imaging. 3 patients received diffusion weighted-imaging(DWI). Results In all five patients,the debris and pus with pus-fluid level were shown inside the lateral ventricle.The debris or pus was slightly hyperintense on T1WI, slightly hypointense on T2WI relative to cerebrospinal fulid(CSF). On DWI, t... |
