摘要

目的评价全脑CT灌注（CT perfusion，CTP）成像在短暂性脑缺血发作（transient ischemic attack，TIA）的临床应用价值。方法对40例临床诊断为TIA的患者行全脑CTP，CTP检查获得达峰时间（TTP）、平均通过时间（MTT）、脑血流量（CBF）、脑血容量（CBV）等参数，同时获得动态CT血管成像（4D-CTA）图像，分析TIA患者的CTP和CT血管造影（CTA）表现。结果 40例TIA患者有36例发现与临床症状相对应的58处异常灌注区。异常灌注区表现为TTP和MTT明显延长，CBF有轻度降低，CBV轻度增高或基本正常。异常灌注区和健侧镜像区TTP值、MTT值和CBF值比较差异均有统计学意义（P0.05），CBV值比较差异无统计学意义（P0.05）。4D-CTA显示责任血管不同程度的狭窄或闭塞，40例TIA患者有32例发现有血管狭窄，2例闭塞，6例正常。结论全脑CTP可以实现对TIA的全面评价，在TIA的诊断及严重程度判断中具有重要价值。

Abstract

Objective To explore the value of whole-brain CT perfusion (CTP) imaging in patients with transient ischemic attack (TIA). Methods Whole-brain CTP was performed in 40 patients with clinically diagnosed TIA. The parameter maps of time to peak (TTP)

mean transit time (MTT)

cerebral blood flow (CBF)

and cerebral blood volume (CBV) were analyzed. Dynamic CT angiography (4D-CTA) images were also obtained. Results Fifty-eight areas of abnormal perfusion changes corresponding to clinical symptoms were found in 36 of the 40 patients with CTP. Prolonged TTP and MTT

decreased CBF and increased or non-changed CBV were detected in the abnormal perfusion areas. The differences of TTP

MTT and CBF of the affected side compared with those of the contralateral side were significant (P0.05)

but the difference of CBV was not (P0.05). 4D-CTA showed responsible vascular stenosis or occlusion in varying degrees. In the 40 patients

vascular stenosis was found in 32 patients

occlusion in 2 patients and normal in 6 patients. Conclusion Overall assessment of TIA can be achieved by whole-brain CTP imaging

which has a great value for the diagnosis and evaluation of TIA.
