【摘要】：目的:评价磁共振扩散加权成像(DWI)和常规序列对新生儿缺氧性脑损伤(非出血灶)的诊断价值,优化磁共振检查序列。方法:54例出生1~14 d临床确诊HIE患儿,分1~7 d患儿和8~14 d患儿,均行3.0T磁共振T1WI、T2WI、FLAIR、DWI扫描,两位磁共振诊断医师采用双盲法观察并记录DWI、T1WI、T2WI和FLAIR图像病灶数目,用秩和检验统计方法,对比分析DWI与常规序列对病灶检出情况,P0.05为差异有统计学意义。结果:出生1~7 d患儿,DWI、T1WI、T2WI、FLAIR检出缺氧性脑损伤病灶分别为196、225、28、365个,平均秩次分别为2.85、2.40、1.29、3.46,Z=60.76,P=0.000。出生8~14 d患儿,DWI、T1WI、T2WI、FLAIR检出缺氧性脑损伤病灶分别为70、141、32、214个,平均秩次分别为1.86、2.89、1.50、3.75,Z=36.34,P=0.000。结论:磁共振DWI联合常规序列对新生儿缺氧性脑损伤具有重要价值,最优化的检查序列DWI、T1WI、FLAIR联合应用。
[Abstract]:Objective: to evaluate the diagnostic value of diffusion-weighted Mr imaging (DWI) and conventional sequences in hypoxic brain injury (non-hemorrhage focus) in neonates, and to optimize the MRI sequence. Methods 54 cases of clinically diagnosed HIE were divided into 1 7 d and 8 d 14 days after birth. All of them underwent 3. 0T MRI T1WIMr T2WIFLAIRI DWI scan. The two MRI diagnostics observed and recorded the number of lesions on DWI T1WIT T2WI and FLAIR images by double blind method, and used rank sum test statistical method. There was significant difference between DWI and conventional sequence in detecting lesions. Results: the detectable lesions of hypoxic brain injury were 196225,28365, and the average rank was 2.852.401.293.46.The average rank of DWII T1WII T2WIFLAIR was 60.76P0.000. The FLAIR of DWII T1WII T2WII was 70141,32214, and the average rank was 1.862.89 / 1.503.75P 0.000, respectively. Conclusion: Mr DWI combined with conventional sequence has important value in neonatal hypoxic brain injury.
