我们应用数字减影血管造影(DSA)进行心腔及小血管造影155例,其中复杂性畸形76例,占50%,最少造影一个系列,最多达6个系列,静脉系统造影286例次,动脉系统造影108例次,逆行肺静脉造影及肺小动脉楔状造影各10例次,结果97%(153/155)均显示清晰的心腔、血管解剖结构。体会是造影剂量明显减少,由于减掉背景象,增加了影象清晰度,根据录相选择有意义图象进行拍片,节省大量胶片。DSA尚有各种图象处理技术,开发了更多诊断领域。 We performed digital subtraction angiography (DSA) for cardiac and angiographic findings in 155 patients, of which 76 were complex and deformed, accounting for 50% of the patients, with at least one series of angiography, up to 6 series, 286 venous angiograms, Systemic 108 cases, retrograde pulmonary venography and pulmonary arteriole wedge radiography in 10 cases, 97% (153/155) showed a clear heart chamber, vascular anatomy. Experience is a significant reduction in the dose of contrast, due to subtract the background image, increased image clarity, according to the video recording meaningful selection of images, save a lot of film. DSA still has a variety of image processing technology, the development of more diagnostic areas.
