摘要:目的:探讨头颅MRI在小儿病毒性脑炎的早期诊断、治疗及判断预后中的应用价值。方法:对35例临床诊断为病毒性脑炎的患儿进行头颅CT和MRI检查,并对结果进行分析。结果:24例患儿行头颅CT检查,16例(66.6%)正常,8例(33.3%)发现病灶14个,病灶显影浅淡,2例病灶明显者1~3个月复查CT,形成大片坏死灶,而8例头颅CT异常者行头颅MRI检查发现病灶30个,病灶清晰且范围较大。35例行头颅MRI检查,8例(22.8%)未见异常,27例(77.1%)发现病灶,病灶达71个。头颅MRI较头颅CT能更早、更多、更清晰发现病灶,病毒性脑炎病灶多不增强。12例单纯疱疹性脑炎行MRI及增强扫描时发现,炎症不累及豆状核,且具有特异性增强扫描特征,10例发现脑白质病变。结论:头颅MRI有助于病毒性脑炎的早期诊断、治疗及判断预后。关键词:头颅MRI; 病毒性脑炎; 儿童
