MRI与超声在新生儿缺氧缺血性脑病诊断中的对比分析

Diagnostic value analysis between MRI and ultrasound in neonate with hypoxic ischemic encephalopathy

目的:采用阿洛卡a10、GE E9彩色多普勒超声诊断仪和GE Signa HDx 3.0 T MRI对新生儿缺氧缺血性脑病(HIE)进行影像学诊断分析,探讨超声、MRI诊断价值及两者间的关系。方法:选择105例确诊为HIE的足月新生儿,出生后2周内分别行彩色多普勒超声和MRI检查。对图像和病理特点进行综合评价,并对诊断结果进行统计学分析。结果:在HIE的分度诊断中,MRI和临床列联系数为0.656 7,P<0.01;超声和临床列联系数为0.637 2,P<0.05;超声和MRI列联系数为0.745 2,P<0.01。结论:MRI与超声在HIE诊断中均发挥重要作用,利用各自的特点可更好地为临床服务。

Objective：To analyze the value of ultrasound and MRI in diagnosis of neonate with hypoxic ischemic encephalopathy （HIE） and to analyze the relationship between the two methods. Methods：105 newborns with HIE were selected. All the cases underwent color Doppler ultrasound and MRI after two-week old. Comprehensive evaluation was made on the image and pathological characteristics,and the diagnosis results were statistically analyzed. Results：Division diagnosis in HIE：MRI and clinical contingency coefficient：0.6567,P〈0.01,US and clinical contingency coefficient：0.6372,P=0.0448,P〈0.05;US and MRI column connection number was 0.74527,P〈0.01. There was a higher coincidence rate of MRI and US in the pathologic diagnosis of HIE. Conclusion：There is a good correlation between MRI and ultrasound in the HIE,and the advantages of their own characteristics should be taken for better clinical services.
