数字减影血管造影(DSA)作为一项新技术,在80年代已广泛用于临床,但对先心病的诊断检查远不如普通心血管造影普遍。其原因主要是心脏搏动易造成运动伪影,影响图像质量。尽管如此,经过一些作者的努力,本法对心脏(包括先心病的心脏)已能获得满意的心脏大血管图像。1982年,Yiannikas对100例先心病患者(其中40例左向右分流)行Ⅳ-DSA,结
As a new technique, digital subtraction angiography (DSA) has been widely used in clinical practice in the 1980s, but the diagnosis of congenital heart disease is far less common than conventional cardiovascular imaging. The main reason is the heart beat easily cause motion artifacts, affecting image quality. In spite of this, after some authors’ efforts, the present law has been able to obtain satisfactory images of cardiac vessels on the heart, including the heart of congenital heart disease. In 1982, Yiannikas on 100 patients with congenital heart disease (40 cases of left to right shunt) IV-DSA, knot
