| 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. |
