| 摘 要： | 目的探讨短暂性脑缺血发作(transient ischemic attack,TIA)患者CT灌注成像(CT perfusion,CTP)的变化,为预防TIA再发提供判断依据。方法经临床确诊的TIA患者20例于急性期先行常规16排螺旋CT横断面平扫,然后根据累及的动脉系统,选择感兴趣平面行脑CT灌注扫描,同时行CT血管造影。1个月后复查脑CT灌注。结果20例患者中,在急性期大部分患者患侧局部脑血流(regional cerebral blood flow,rCBF)呈轻到中度异常,患侧局部脑血容量(regional cerebral blood volume,rCBV)呈正常或轻度下降。1个月后复查CT脑灌注结果显示有12例患者未发现异常,8例患者rCBF呈轻到中度下降,患侧rCBV呈正常或轻度下降,随访1年,14例未复发。6例两次CT灌注均有异常者在1年内有5例TIA再发,1例发展为脑梗死。结论对于脑灌注量降低严重而且持续时间长的TIA患者,提示可能出现TIA再发或进展为脑梗死,应及时强化抗缺血治疗。

| Abstract: | Objective Evaluation of cerebral blood flow in patients with transient ischemic attack (TIA) using cerebral CT perfusion imaging. Methods CT perfusion scan was performed on a consecutive series of 20 patients with clinical definite TIA. Following their initial CT scan at acute stage of TIA, patients underwent two repeat CT perfusion scanning of region of interest at acute stage and one month after symptom remission. Results Mild to moderate decrease in regional cerebral blood flow (rCBF) and unchanged or mi... |
