摘　　要：目的本研究旨在分析螺旋CT灌注成像在早期诊断急性缺血性脑血管病中的应用效果情况。方法选取2019年3月—2019年12月间于我院诊疗的初诊为急性缺血性脑血管病的患者共计72例,分别于入院后立即行CT平扫,而后进行CT灌注成像扫描。扫描后对患者的检查结果进行统计学分析。结果通过CT平扫确诊存在脑梗死病灶患者33例,未发现明确病灶患者39例;通过CT灌注成像确诊存在脑梗死病灶患者67例,未发现明确病灶患者5例,其中病灶中心同周围正常区域比较,脑血流量、对比剂峰值时间、脑血容积及平均通过时间比较均存在统计学差异(P<0.05)。结论螺旋CT灌注成像诊断急性缺血性脑血管病的敏感性、准确性均优于CT平扫,值得推广。Objective To analyze the effect of spiral CT perfusion imaging in early diagnosis of acute ischemic cerebrovascular disease.Methods Selected 72 patients with diagnosed acute ischemic cerebrovascular disease from March 2019 to December 2019,and plain CT scans were performed immediately after admission,followed by CT perfusion imaging scans.After the scan,the patient's examination results were statistically analyzed.Results 33 patients with cerebral infarction were diagnosed by CT plain scan,and 39 patients with no clear lesions were found.67 patients with cerebral infarction lesions were confirmed by CT perfusion imaging,and 5 patients with no clear lesions were found.There were statistical differences in cerebral blood volume,cerebral blood flow,peak contrast time,cerebral blood volume and mean transit time(P<0.05).Conclusion The sensitivity and accuracy of spiral CT perfusion imaging in the diagnosis of acute ischemic cerebrovascular disease are better than plain CT scans,and it is worth popularizing.
