摘要

目的:探讨脑血管造影系统在脑c臂ct灌注成像(c臂CTP)中的新应用。病例介绍:c臂CTP方案连续收集10次前后c臂旋转的x射线投影图像。根据采集到的数据，重建脑血流量(CBF)、脑血容量(CBV)、平均传输时间(MTT)、峰值时间(TTP)图像和多相血管图像。c臂CTP图像获得的患者急性和慢性大动脉闭塞。结论:采用血管造影系统的c臂CTP能够实时评估灌注参数，与传统的多排CT灌注评估(MD-CTP)相似，提示其在血管造影套件中对缺血性脑卒中的检查具有实用价值。

C-arm CT Perfusion Study Using Angiography System

Objective: A newly developed application for cerebral C-arm computed tomography perfusion imaging (C-arm CTP) using an angiography system was investigated. Case Presentation: C-arm CTP protocol continuously collects X-ray projection images during 10 back and forth C-arm rotations. From the collected data, cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), and time to peak (TTP) images and multiphase vascular images are reconstructed. C-arm CTP images acquired in patients with acute and chronic major artery occlusion are presented. Conclusion: C-arm CTP using an angiography system is capable of evaluating perfusion parameters in real time, similar to conventional evaluation using multi-detector row CT perfusion (MD-CTP), suggesting its usefulness for examination of ischemic stroke in the angiographic suite.
