摘要
目的:探讨磁敏感加权成像(SWI)序列在颅脑损伤诊断及伤情和预后评估中的价值。方法:收集2017年1月-2018年8月40例颅脑外伤患者,行CT平扫、MRI常规序列及SWI序列检查,检测各方法显示颅内出血灶数量;并分析SWI序列所发现出血灶数量和体积与GCS、GOS评分相关性。结果:40例患者中SWI序列共检出血灶420个,T1WI上206个,T2WI上225个,FLAIR上279个,CT上186个。40例患者以GCS评分分为轻度、中度、重度三组,经Spearman相关分析表明出血灶的数目和体积与患者的GCS、GOS评分呈负相关。结论:SWI中发现的出血灶数量多于MR常规序列及CT显示的病灶,SWI显示出血灶的数目和体积与GCS、GOS评分呈负相关,出血灶数目越多、体积越大,GCS、GOS评分越低,颅脑损伤越重、预后越差。
Purpose:To explore the value of susceptibility-weighted imaging(SWI)sequence in the diagnosis of craniocerebral injury and the evaluation of injury and prognosis.Methods:Forty patients with head injury from January 2017 to August 2018 were undergone with CT scan,MRI scan with routine sequence and SWI sequence.The intracranial hemorrhagic lesions detected by various methods were recorded.The correlation between the number and the volume of hemorrhagic lesions detected by SWI and the GCS,GOS score was analyzed.Results:Four hundred and twenty lesions were detected in 40 patients on SWI,206 lesions on T1WI,225 lesions on T2WI,279 lesions on FLAIR and 186 lesions on CT.All the patients were divided into three group according to the GCS scores:mild,moderate and severe.Spearman correlation analysis showed that the number and the volume of hemorrhagic lesions were negatively correlated with GCS,GOS scores.Conclusion:The number of hemorrhagic lesions found in SWI was significantly greater than that in MR routine sequence and CT.The number and volume of hemorrhagic lesions detected in SWI were negatively correlated with GCS and GOS scores.The larger the number of bleeding lesions and the larger the volume,the lower the GCS and GOS scores,the heavier the brain injury,and the worse the prognosis.
