摘要：目的：研究磁共振SWI和PWI在急性缺血性脑梗死缺血半暗带量化评定中的应用。方法：选择自2019年6月至2020年8月来我院就诊的124例急性缺血性脑梗死患者作为本次研究对象，采用数字表法将124例患者随机平均分为A组和B组，每组62例。A组进行磁共振SWI扫描，B组进行磁共振PWI扫描。对比两组对急性缺血性脑梗死缺血半暗带量化评定结果。结果：A组检出率小于B组检出率，但两组差异无统计学意义（P>0.05）;A组病灶检出率低于B组，两组差异有统计学意义（P<0.05）。结论：SWI对急性缺血性脑梗死患者缺血半暗带整体检出率与PWI没有明显差异，说明SWI可以用于急性缺血性脑梗死患者脑梗死半暗带筛查，且与PWI相比对人体损伤较小，有推广应用的价值。

Abstract： Objective： To study the application of SWI and PWI in quantitative assessment of ischemic penumbra in acute ischemic cerebral infarction. Methods： 124 patients with acute ischemic cerebral infarction from June 2019 to August 2020 in our hospital were selected as the research objects， and they were randomly divided into group A and group B with 62 cases in each group. Group a underwent SWI and group B underwent PWI. The quantitative evaluation results of ischemic penumbra in the two groups were compared. Results： the detection rate of group A was lower than that of group B， but there was no significant difference between the two groups （P>0.05）; The detection rate of lesions in group A was lower than that in group B， and the difference was statistically significant（P<0.05）. Conclusion： there is no significant difference between SWI and PWI in the detection rate of ischemic penumbra in patients with acute ischemic cerebral infarction， indicating that SWI can be used to screen ischemic penumbra in patients with acute ischemic cerebral infarction， and has less damage to human body compared with PWI， which has the value of popularization and application.

近年來心脑血管疾病的患病率一直居高不下，而且整体呈现上升态势，严重威胁着人们的生命健康[1]。心脑血管疾病中急性缺血性脑梗死的患者基数极大，由于各种原因导致患者脑血管堵塞，致使该血管供血区域的细胞无法接受供养，发生大片梗死。但长期研究发现，在患者出现脑梗死后如果能够及时进行重新灌注治疗，部分处于梗死区域的细胞可以恢复正常的生理功能。目前研究的重点在于如何鉴别可恢复细胞并进行及时再灌注治疗，让这些细胞恢复正常[2]。脑细胞是不可再生细胞，一旦丧失生理功能将无法进行修复，而脑细胞又对人体各部分都有着重要的影响，所以探索更加方便灵敏的缺血半暗带诊断方法，从而让患者获得更好的治疗具有重要意义[3]。基于此，选择自2019年6月至2020年8月来我院就诊的124例急性缺血性脑梗死患者作为本次研究对象，采用数字表法将124例患者随机平均分为A组和B组，每组62例。A组……
