目的 综合分析CT灌注联合CT 造影在缺血性脑卒中患者中的诊断效 果，为治疗缺血性脑卒中患者提供科学 的数据参考。方法 选取我院在2015年 3月-2016年2月收治的缺血性脑卒中患 者临床资料28例，采用SPSS21.0统计学 软件进行统计学分析两种检查方法对患 者的脑组织灌注异常情况、颅内血管狭 窄情况以及诊断一致性。结果 灌注异 常区的脑血容量、对比剂峰值时间、脑 血流流量、对比剂平均通过时间分别为 (4.26±0.54)ml/100g、(25.16±3.22) s、(39.66±15.23)ml/100g·min、 (5.23±0.67)s，镜像区的脑血容量、对 比剂峰值时间、脑血流流量、对比剂平均 通过时间分别为(5.35±0.84)ml/100g、 (24.91±3.23)s、(56.24±15.61) ml/100g·min、(4.01±0.68)s，脑血容 量、脑血流流量、对比剂平均通过时间比 较有统计学意义(P<0.05)，对比剂峰值时 间比较无统计学意义(P>0.05)；联合检查 结果发现：28例患者存在责任血管情况为 4例，阳性率为14.26%(4/28)，28例患者 不存在责任血管情况为20例，阳性率为 71.43%(20/28)，两组检查结果比较差异 有统计学意义(P<0.05)。结论 CT灌注联 合CT造影在缺血性脑卒中患者中的诊断效 果能够提供更多有用的价值信息，准确反 映脑组织血流动力学变化，为临床诊断提 供参考依据。

Objective To analyze the diagnostic effect of CT perfusion combined with CT angiography in patients with ischemic stroke, and to provide scientific data for the treatment of ischemic stroke patients. Methods Selection of our hospital in March 2015- 2016 February treated ischemic cerebral stroke in patients with clinical data of 28 cases, by spss21.0 statistical software for statistical analysis of the two kinds of inspection methods for patients of cerebral perfusion abnormalities, intracranial vascular stenosis and consistent with a diagnosis of. Results Agent/100g respectively were abnormal perfusion of cerebral blood volume, contrast agent peak time, cerebral blood flow, contrast agent mean through time (4.26+0.54)/100g, (251600+3.22)s, (39.66+15.23)/100g·min, (5.23+0.67)s, the mirror area of cerebral blood volume, contrast agent peak time, cerebral blood flow, contrast agent mean through time (5.35+0.84)/100g, (24.91+3.23)s, (56.24+15.61)- min, (4.01 and 0.68)s, cerebral blood volume, cerebral blood flow, contrast agent mean through time compared with statistical significance (P<0.05), compared to the peak time is no statistical significance (P>0.05). The joint inspection results: 28 cases of patients with vascular responsibility for 4 cases, the positive rate was 14.26% (4/28), 28 cases of responsible vessels for 20 cases of the patients does not exist, the positive rate is 71.43% (20/28), the examinations of the two groups the difference has statistical significance (P<0.05). Conclusion CT perfusion combined with CT angiography in the diagnosis of ischemic stroke patients can provide more useful information to accurately reflect the changes in cerebral hemodynamics, to provide a reference for clinical diagnosis.
