磁敏感加权成像诊断新生儿颅内出血临床价值研究

Applications of susceptibility weighted imaging to the clinical treatment for intracranial hemorrhage of the newborn

目的对比分析新生儿颅内出血在磁敏感加权成像(SWI)与常规磁共振成像(MRI)的影像表现,探讨SWI在评价新生儿颅内出血的临床应用价值。方法本研究收集2009年12月至2011年8月中国医科大学附属盛京医院临床拟诊的新生儿颅内出血40例,行3.0 T头MRI及SWI检查,确诊的29例患儿入组。分析患儿MRI表现,比较SWI与常规MRI显示新生儿颅内出血的敏感性。结果 SWI共检出29例新生儿颅内出血,MRI常规序列仅检出其中的21例,在脑微量出血16例中SWI发现65个病灶,常规MRI序列发现43个病灶。结论 SWI对于新生儿颅内出血诊断及脑微出血病灶的显示与常规MRI成像扫描序列相比,具有很高的敏感性。

Objective To observe the imaging characteristics of cerebrovascular disease using the susceptibility weight- ed imaging and conventional magnetic resonance imaging, and investigate the clinical significance of susceptibility weighted imaging in detecting intracranial hemorrhage of newboru.Methods In this study, 40 cases of cerebral micro- bleeds were collected and analysed.All of the patients were scanned with conventional MRI resonance and SWI.SWI se- quence was compared with the conventional MRI sequences in detecting and diagnosing intracranial hemorrhage of the newborn and the superiority of the SWI in showing the cerebrovascular disease. Results The 29 cases of cerebrovascu- lar disease were confirmed by SWI, only 21 of 29 cases were found by conventional MR sequences. Altogether 65 hemor- rhagic lesions were detected by SWI, while only 43 were found by conventional magnetic resonance imaging. Conclu- sion SWI sequence has more sensitivity than conventional sequences in detecting the intracranial hemorrhage of the newborn.
