| 摘 要： | 目的评价功能磁共振在单纯疱疹病毒性脑炎中的诊断价值。方法本例患者女性,45岁,行CT、MRI常规扫描及核磁血管成像、弥散加权成像、灌注成像,结合实验室检查、临床表现诊断单纯性疱疹性病毒性脑炎。结果发病当日CT平扫未见异常,6天后CT平扫右侧颞叶皮层大片状低密度,MRI右侧颞叶累及皮层、皮层下白质大面积长T1长T2高Flair信号,弥散加权成像呈高信号,ADC值较对侧低22%～36%,灌注成像右颞病变相对脑血流量及体积较对侧明显增高;MRA右侧大脑中动脉血管分支明显增粗、数目增多。结论当传统CT及MRI平扫及增强扫描难以鉴别脑梗死与脑炎时,功能MRI成像有助于单纯疱疹脑炎定性诊断。

| Abstract: | Objective To evaluate the role of function magnetic resonance imaging(FMRI)in the diagnosis of one side herpes simplex encephalitis(HSE).Methods Conventional computed tomography(CT)and magnetic resonance imaging(MRI)including T1-WI,T2-WI,fluid attenuated inversion recovery(Flair)sequences and MRA and diffusion-weighted imaging(DWI)and perfusion-weighted imaging(PWI)were obtained in a 45 years old female patient with HSE diagnosed on the basis of laboratory,clinical and radiologic findings.Results CT was nor... |
