新生儿缺氧缺血性脑损伤中的少量出血灶在磁敏感加权序列的成像研究

Magnetic Susceptibility Weighted Imaging Study of Small Amount of Hemorrhage in Neonatal Hypoxicischemic Brain Damage

目的探讨磁敏感加权序列(SWI)在显示新生儿缺氧缺血性脑损伤(HIBD)出血灶的应用价值。方法分析53例新生儿缺氧缺血性脑损伤患儿,利用SWI序列检测出血灶,分析磁敏感加权成像在不同部位出血灶的检出情况。结果 SWI检出HIBD足月儿颅内出血(12例),早产儿颅内出血(41例);其中侧脑室内出血(23例)、脑实质内出血(14例)、蛛网膜下腔少量出血(16例)。结论 SWI对于新生儿HIBD中出血的检出具有很高的敏感性和特异性。

Objective To investigate the application of susceptibility weighted imaging（SWI） in the diagnosis of small intracranial hemorrhage in neonates. Methods Retrospective analysis of 53 cases of neonatal intracranial hemorrhage diagnosed by susceptibility weighted imaging,analysis of magnetic susceptibility weighted imaging in neonatal,premature infants,intracranial hemorrhage in different parts of the detection. Results Susceptibility weighted imaging detection of full-term infants with intracranial hemorrhage（12 cases）,premature infants with intracranial hemorrhage（41 cases）; the interior side of cerebral hemorrhage（23 cases）,intracerebral hemorrhage（14 cases）,subarachnoid hemorrhage（16 cases）. Conclusions Susceptibility weighted imaging is an effective method for detecting small intracranial hemorrhage in neonates.
