Fast cine phase contrast magnetic resonance angiography (PC-MRA) has the potential to provide a quantitative measurement method for the diagnosis and treatment of cerebrovascular disease. To evaluation the changes of cerebral blood flow and the characteristics of artery lesion distribution in the patients of transient ischemic attacks (TIA). In all, 98 normal subjects and 106 TIA patients who underwent MRI examination within 72 h after the last symptom onset including the DWI sequence to exclude acute cerebral infarction were enrolled. The blood flow of the cranial total, the area of the internal carotid artery and vertebral artery, the average velocity, and the average blood flow were obtained and compared in normal subjects and TIA group. Analysis of Variance (ANOVA), -test, and Kruskal-Wallis test were used for statistical assessments. The total cerebral blood flow of the TIA group and normal control group was no significant statistical difference (). The total blood flow decreased with increasing age, and the TIA group was much lower than the control group. The blood flow of the right internal carotid artery in the TIA group had a significant difference compared with controls (). However, the same situation did not happen in both of the left internal carotid artery and vertebral artery. Phase contrast magnetic resonance imaging has the potential to evaluate the change of cerebral blood flow in TIA patients. The decrease in the total blood flow and the symptom onset of TIA is consistent. Phase contrast magnetic resonance imaging could provide guidance to the diagnosis of TIA.

快速Cine相差磁共振血管造影对短暂性脑缺血发作患者脑血流动力学的评估。

快速电影相衬磁共振血管造影（PC-MRA）有潜力为脑血管疾病的诊断和治疗提供定量测量方法。评估短暂性脑缺血发作（TIA）患者脑血流的变化和动脉病变分布的特征。纳入了98名正常受试者和106名TIA患者，他们在最后一次症状发作后72小时内接受了MRI检查，包括DWI序列以排除急性脑梗死。并比较了正常受试者和TIA组的颅总血流量，颈内动脉和椎动脉的面积，平均速度和平均血流量。方差分析（ANOVA），-检验和Kruskal-Wallis检验用于统计评估。TIA组和正常对照组的总脑血流量无统计学差异（）。随着年龄的增长，总血流量减少，TIA组远低于对照组。TIA组右颈内动脉的血流与对照组相比有显着性差异（）。但是，左颈内动脉和椎动脉都没有发生相同的情况。相衬磁共振成像有潜力评估TIA患者脑血流的变化。总血流量的减少和TIA的症状发作是一致的。相衬磁共振成像可以为TIA的诊断提供指导。
