This study reports on the optimization of this technique and the first clinical results in comparison with conventional screen-film angiography and digital subtraction angiography (DSA) in single steps. For each method, 25 angiograms were interpreted to compare the image quality, the radiation ...
数字减影血管造影(digital subtraction angiography,DSA) DSA是基于顺序图像的数字减影,将未造影的图像和造影后图像分别经影像增强器增强,摄像机扫描而矩阵化,经模/数转换成数字化,两者相减而获得数字化图像,最后复经数/模转换成减影图像,此即DSA技术。该技术主要优点是图像中没有原来的骨与软组织影,故显示清楚,因其...
DSA(DigitalsuBtraCtionangiography) 相关知识点: 试题来源: 解析 即数字减影血管造影,是应用计算机处理数字化影像信息技术,以消除骨骼和软组织影像,突出显示血管影像。它分为动脉法和静脉法两种。前者血管显影较清晰,对比剂用量减少,但需行动脉内导管术,患者有一定的痛苦。
血管造影X射线系统(Digital Subtraction Angiography) 血管造影X射线系统(Digital Subtraction Angiography),近几年来被各大医院广泛使用,主要用于心、脑、外周血管疾病的造影检查和介入治疗。DSA和常规血管造影检查相比具有造影剂量小、时间短、对病人侵害小等特点。该系统具有强大的高级功能模块,如类CT软组织成像、实时介入...
