摘要
目的 研究头颅核磁共振 (MRI)对病毒性脑炎的早期诊断价值。方法 观察 10例病毒性脑炎患者头颅 CT、MRI表现 ,其中 8例行增强扫描 ,5例行快速液体衰减反转回复 (FL AIR)检查。结果 头颅MRI较 CT发现更多病灶 ,其病灶多不增强 ,FL AIR技术可以更清晰地发现病灶。其中单纯疱疹病毒性脑炎的 MRI更有其特征性表现。结论 头颅 MRI有助于病毒性脑炎的早期诊断。
Objective To investigate the diagnosis value of cranial MRI in the early stage of virus encephalitis.Methods CT and MRI manifestations in 10 adult patients with virus encephalitis were investigated,8 of them with postcontrast and five of 8 with FLAIR examination.Results More focuses were seen on MRI than on CT. They were seldom made postcontrast. Focus were found clearer with FLAIR technique.MRI of herpes simplex encephalitis in them had its characteristic manifestation.Conclusion Cranial MRI contributed to early stage diagnosis of virus encephalitis.
