摘要目的由于侧支循环状态不同,CT血管成像(CTA)动脉早期有可能高估血栓长度。本研究评价基于双期CT所见血栓长度不一致性的分级系统对评估预后的价值。方法纳入48例大脑中动脉M1段闭塞的急性缺血性脑卒中病人。CT双期扫描程序包括平扫、对比剂团注跟踪技术CTA以
Abstract Purpose Due to the different status of collateral circulation, CT angiography (CTA) arteries may overestimate the length of thrombus early. This study evaluates the value of a classification system based on inconsistency of thrombus length seen in double-phase CT in assessing prognosis. Methods A total of 48 patients with acute ischemic stroke with occlusion of M1 segment of the middle cerebral artery were enrolled. CT double-phase scanning procedures include CTA, contrast agent bolus technique CTA
