Purpose: To explore the feasibility of low-dose CT perfusion (CTP) technique in evaluating the cerebral blood flow in patients with moyamoya before and alter operation.Method:The study was approved by the local ethical committee and written informed consent was obtained from all subjects.Four patients with moyamoya proved by DSA were scanned within 7 days before and after the operation on a dual-source dual-energy(DSDE)CT(Siemens definition flash)with low-dose perfusion sequence.

目的:介入放射学是近年来兴起并迅速发展的一门融医学影像、临床诊断、治疗学为一体的边缘学科.以其创伤小、患者痛苦小、临床效果好等优点,深受患者和医务人员的欢迎,它给人类带来了诸多方便,但同时也对人体造成了很多损伤.文章从多方面分析了介入放射防护中存在的问题,并提出合理化建议.
目的:测量和评价冠心病介入治疗中第一术者在重要辐射剂量区域内的辐射吸收剂量,为操作者的辐射防护提供指导和帮助.方法:选用冠心病介入治疗中常用的七个体位,分别在没有辐射防护和有上下防护情况下测定不同高度第一术者体表入射剂量率,并绘制体表入射剂量率分布图,对结果进行比较分析.
