摘要
目的探讨新生儿缺氧缺血性脑病(HIE)患儿磁共振多序列分度与临床分度的一致性。方法将经临床确诊为HIE的新生儿95例进行包括DWI及ESWAN序列的MRI多序列扫描,分别比较不同序列组合的MRI分度与临床分度的一致性。结果 T1WI组MRI分度与临床分度比较Kappa值为0.32(P<0.05),一致性较差;T1WI+DWI组MRI分度与临床分度比较Kappa值为0.57(P<0.05),一致性上升;T1WI+DWI+ESWAN组MRI分度与临床分度比较Kappa值为0.79(P<0.05),一致性好。结论 T1WI联合DWI及ESWAN序列后,明显提高了HIE MRI分度与临床分度的一致性。
Objective To investigate the consistency of multiple - sequence magnetic resonance grading and clinical grading of HIE in children. Methods 95 new - born children confirmed diagnosis of HIE were proceeded with MRI multiple - sequence scanning including DWI and ESWAN sequences. The conformity of different sequence groups＇ MRI grading and clinical grading was compared respectively. Results Compared clinical grading and MRI grading, the kappa value in group T1WI was 0.32 （P 〈 0.05 ）, a poor consistency;the kappa value was 0.57 in group T1WI ＋ DW （P 〈 0.05 ）, which consistency was better;the kappa value was 0.79 in group T1WI ＋ DWI ＋ ESWAN （P 〈 0.05）, a well consistency. Conclusion TI WI combined with DWI and ESWAN sequences can signifi- cantly improve the consistency of MRI grading and clinical grading on HIE.
