摘要
目的探讨在早期小儿病毒性脑炎中应用磁共振及弥散加权成像的应用价值。方法选取2015年5月~2016年11月在医院接受治疗的25例早期小儿病毒性脑炎患儿作为研究对象,分析患儿的磁共振和弥散加权成像资料,分析磁共振成像的早期表现。结果经DWI检查,均能显示所有的病灶,经常规MRI检查,其中有16例患儿的病灶呈现斑片状和大片状的异常信号,其中T1W1显示为稍低信号、T2W1显示为稍高信号,且两类信号均显示均匀,边界不清晰。经T2Flair均显现为稍高信号,DWI序列为高信号,ADC的融合度均未低信号;无论病变部位出现在何处,病灶区的ADC明显低于健侧,且组间差异具有统计学意义(P<0.05)。结论在早期小儿病毒性脑炎中应用磁共振诊断,具有一定的特征,应用弥散加权成像能早期发现病灶,在临床诊断中具有一定价值。
Objective To discuss the clinical value of magnetic resonance imaging and diffusion weighted imaging in early diagnosis of viral encephalitis in children. Methods Twenty-five cases of patients with early childhood viral encephalitis in our hospital from May 2015 to November 2016 were collected as subjects. Magnetic resonance imaging and diffusion weighted im-aging were performed to analyze the early manifestation of MR imaging. Results All lesions were detected by DWI examina-mong which T1W1 showed slightly low signal, T2W1 showed slightly high signal and two signal showed uniform, the bound-ary was not clear. All of them showed a slightly higher signal after T2Flair, and the DWI sequence was high signal, and the fusion degree of ADC was low. No matter where the lesion occurred, the ADC in the lesion area was significantly lower than that in the uninjured side, and the difference between the two groups was statistically significant （P〈C〇 . 05）. Conclusion In early childhood viral encephalitis, the use of magnetic resonance imaging had certain characteristic, and diffusion weighted im-aging could early detect lesions, which had certain value in clinical diagnosis.
