磁共振序列对儿童病毒性脑炎的诊断意义

摘要(Abstract)：
目的探讨不同磁共振序列MRI、DWI、ADC值、MRS在儿童病毒性脑炎的诊断意义。方法对36例病毒性脑炎患儿的MRI、DWI、ADC值、MRS与临床资料进行回顾性比较分析。结果Ⅰ组(n=15)DWI优于常规MRI,Ⅱ组(n=9)DWI与常规MRI基本一致,Ⅲ组(n=10)常规MRI优于DWI。3组ADC值与发病时间呈显著正相关(P<0.01);按病情轻重分组,轻度损伤组(GCS 9~15分)28例,重度损伤组(GCS 3~8分)8例,病变区域检测NAA/Cho降低,比值降低与病情损害程度呈正比,组间比较差异有统计学意义(P<0.01)。结论综合研判磁共振不同序列表现及其变化值,对儿童病毒性脑炎的早期诊断、病情评估具有重要价值。
