| 摘 要： | 目的利用CT灌注成像技术研究慢性大动脉狭窄或闭塞患者的脑血流灌注特征。方法搜集具有完整临床资料的单侧慢性大脑中动脉重度狭窄或闭塞患者11例,行CT灌注成像及磁共振（MRI及MRA）检查。结果慢性大脑中动脉狭窄或闭塞患者的脑CT灌注特征是患侧脑血流量（CBF）降低,脑血容量（CBV）升高,平均通过时间（MTT）延长。结论 CT灌注成像能反映慢性大脑中动脉狭窄或闭塞患者的脑血流灌注特征,为临床治疗方案的制订提供理论依据。

| Abstract: | Objective To evaluate the blood perfusion character of chronic middle cerebral artery stenosis or occlusion with CT perfusion imaging.Methods The clinical and imaging data of 11 cases with unilateral chronic middle cerebral artery stenosis or occlusion were collected.All cases were examined with CT perfusion and MR(MRI and MRA).Results The CT perfusion character of chronic middle cerebral artery stenosis or occlusion included CBV elevated,CBF decreased,and MTT prolonged.Conclusion CT perfusion imaging can describe the blood perfusion character of chronic middle cerebral artery stenosis or occlusion,and provide theoretical basis for therapeutic plan. |
