3.0T磁共振对新生儿HIE诊断价值和检查序列优化
Value of 3.0T Magnetic Resonance Imaging in the Diagnosis of Neonatal HIE and Optimization of Examination Sequence
摘要
Abstract
Objective:To evaluate the diagnostic value of the magnetic resonance(MRI) diffusion weighted imaging (DWI) and T1WI、T2WI、FLAIR in the diagnosis evaluation of hypoxic-ischemic encephalopathy(HIE),optimizing examination process of magnetic resonance.Method:A total of 54 neonatal clinical definited HIE including 1-14 days age were examined using DWI and routine T1WI,T2WI,FLAIR of 3.0T MR,54 neonatal divided into 1-7 days age and 8-14 days age,the brain injury lesion in T1WI,T2WI, FLAIR,DWI were diagnosed by two senior radioloists,the contrastive analysis of DWI,T1WI,T2WI,FLAIR findings were tested by using Wilcoxon rank sum test.P<0.05 was considered as statistical.Result:In 36 cases of 1-7 days,196 brain injury lesions were found by DWI and 225 brain injury lesions by T1WI,28 brain injury lesions by T2WI,365 brain injury lesions by FLAIR.Mean rank order of DWI,T1WI,T2WI,FLAIR were 2.85,2.40, 1.29,3.46,Z=60.76,P=0.000.In 18 cases of 8-14 days age,70 brain injury lesions were found by DWI and 141 brain injury lesions by T1WI,32 brain injury lesions by T2WI,214 brain injury lesions by FLAIR.Mean rank order of DWI,T1WI,T2WI,FLAIR were 1.86,2.89,1.50,3.75,Z=36.34,P=0.000.Conclusion:Magnetic resonance DWI combiened with conventional MRI is important in the diagnosis evaluation of neonatal HIE,the optimal sequence of MRI is DWI and T1WI,FLAIR combined application.关键词
