摘　　要：目的分析对比磁共振磁敏感成像(susceptibility weighted imaging,SWI)和CT检查在诊断小儿颅内出血的价值。方法回顾性分析我院临床确诊颅内出血的患儿23例发病3天内进行头颅磁共振SWI成像和CT横切位扫描检查,对SWI成像和CT检查图像进行分析评分比较。结果 23例共有出血灶69个,SWI成像发现出血者23例,出血灶共69个,检出率为100%;CT扫描发现出血者21例,出血灶共29个,检出率为91.3%。两者对小儿颅内出血检出率差别有统计学意义(P<0.05)。结论 SWI对小儿颅内出血的敏感度高,其检出率明显高于CT,对颅内出血的小儿的诊断和治疗有显著的价值。Objective To analyze contrast MR susceptibility imaging （susceptibility weighted imaging, SWI） and CT examination of the value in the diagnosis of intracranial hemorrhage in children. Met.lzods A retrospective analysis of hospital clinical diagnosis of intracranial hemorrhage in children of 23 cases within 3 days of onset SWI imaging of the brain magnetic resonance and CT cross-section scan, score on SWI imaging and CT scan images were analyzed. Results 69 of 23 cases of a total of hemorrhage and the SWI imaging found 23 cases of bleeding, a total of 59 bleeding lesions, the detection rate of 100%; CT scan found 21 cases of bleeding, bleeding lesions, 29, was detected in 91.3 %. Two children with intracranial hemorrhage detection rate difference was statistically significant （P 〈0.05）. Conclusion SWI sensitivity in children with intracranial hemorrhage, the detection rate was significantly higher than CT, a significant value on tile diagnosis and treatment of children with intracranial hemorrhage.
