ABSTRACT
Objective To explore the application of the tracking scan technique in 16-slice spiral CT angiography, in order to improve the quality of CTA. Methods Three hundred patients who were divided into three groups randomly underwent CTA in tracking, testing and estimation scan respectively with GE LightSpeed 16-slice spiral CT. The data of all patients were transmitted to the workstation (AW4.2) and reconstructed. The quality of all images were evaluated by three experienced doctors with double-blind method and divided into four grades (A, B, C and D) from optimal to poor. Results The rate of grade A, B, C and D was 89.00%, 7.00%, 4.00% and 0 respectively for tracking scan, 70.00%, 11.00%, 15.00% and 4.00% respectively for testing scan, while 61.00%, 13.00%, 21.00% and 5.00% respectively for estimation scan. Conclusion Tracking scan technique is superior to testing and estimation scan in image quality of 16-slice spiral CT angiography.
