Abstract
Objective: To discuss the methods and experience of 64-slice spiral CT which used in infant cases with congenital heart disease, to select the appropriate scan parameters for reducing artifact and the radiation dose. Methods: Thirty-five cases with congenital heart disease were arranged CT examination by using Philips Brilliance 64-slice spiral CT scanner with Blous Tracking techniques. Results: All the images of the heart chambers, pulmonary artery, pulmonary vein, the ascending aorta and the descending aorta contrast agent filling showed good and had clear display. The density of superior vena cava is moderate. The various vascular CT value is approximate, no hardening artifacts. The atrioventricular of Cardiac and vascular of contrast agent filled fully and had clear boundary, no significant artifacts and no effect on the impact reconstruction. Conclusion: Appropriate adjustment of scanning parameters can reduce hardening artifact and the impact of artifacts. Following the principle of as low as reasonably achievable (ALARA) can obtain diagnostic images and reduce radiation damage to the infant.关键词
