摘　　要：目的通过比较与分析CT脑灌注(CTPI)与血管造影(CTA)用于临床急性缺血性脑卒中诊断价值,从而可为临床急性缺血性脑卒中患者诊断与治疗提供参考。方法选取本院58例急性缺血性脑卒中患者作为本次研究对象,采用CT对患者进行头颈部CTPI、CTA检查。统计两组诊断情况,并加以比较与分析。结果经检查发现,CT灌注图中,其中与患者临床症状相对应的灌注异常处共为50例,阳性率为86.2%明显高于CT检查16例,阳性率27.6%,P<0.05。灌注异常区CBV和CBF及MTT参数值与临床镜像健侧比较,P<0.05;经CTA检查发现,患者共存在10处单纯颈内动脉狭窄、20处单纯颅内动脉狭窄、8例颈内动脉且颅内动脉狭窄。联合CTA与CTPI检查发现,责任血管者采用CTPI检查阳性者38例,阳性率为65.5%明显高于无责任血管者12例,占20.7%,P<0.05。结论临床应用CT脑灌注与血管造影可较好地诊断急性缺血性脑卒中,从而为临床诊断、预防及治疗提供重要参考价值。Objective By comparison and analysis of brain perfusion CT（CTPI） and angiography（CTA） for the diagnosis of acute ischemic stroke clinical value, which can provide a reference for clinical diagnosis of acute ischemic stroke patients and treatment.Methods Select the hospital 58 cases of acute ischemic stroke patients as this study, the use of CT in patients with head and neck CTPI, CTA examination. Statistics groups of diagnosis, and compared and analyzed. Resultslts The inspection found, CT perfusion figure, which corresponds with the clinical symptoms of perfusion abnormalities at a total of 50 cases, the positive rate of 86.2% was significantly higher than that of CT examination in 16 cases, the positive rate of 27.6%,P〈0.05. Perfusion abnormalities area CBV and CBF and MTT compare parameter values and clinical mirrored contralateral,P〈0.05; by CTA examination revealed that the patient simply co-exist within the 10 carotid stenosis, 20 intracranial arterial stenosis alone, eight cases of internal carotid artery and intracranial arterial stenosis. CTA and CTPI joint inspection found offending vessels were using CTPI test positive in 38 cases, the positive rate of 65.5% was significantly higher than those without offending vessels were 12 cases, accounting for 20.7%, P〈0.05. Conclusion Conclusion The clinical application of CT brain perfusion and angiography may be better diagnosis of acute ischemic stroke, which is a clinical diagnosis, prevention and treatment provide important reference value.
