Abstract: Given the unique advantages of dual-source computed tomography(DSCT), such as high temporary and spatial resolutions and fast scanning speed, its application in angiography has made possible for high-quality images to be obtained. In high-pitch scanning mode, DSCT can obtain high-quality angiography images with low effective radiation dose at a short scan time. This paper reviewed the progress and clinical applications of high-pitch mode DSCT in computed tomography angiography.
