Title: $Application of 16-slice spiral CT coronary angiography
Abstract: [Objective] To discuss the method of 16-slice spiral CT coronary angiography and the factors that influence the image quality.[Methods] There were 43 cases.By virtue of retrospective electro-cardiographical(ECG)-gated technology and heart CT autoscanning conditions,total of 43 patients were performed with plain CT scan and contrast-enhanced CT imaging.Coronary artery images were reconstructed by different special software techniques.[Results] Among the 43 patients,the heart-rate,the coronary artery and the clearly demonstrated coronary artery,relatively and respectively,were below 60/min,52,39(75%)and 60~70/min,88,66(75%)and 70~80/min,32,23(71.9%).[Conclusion] The 16-slices spiral CT coronary angiography is a potential,noninvasive method for the screening of coronary artery disease and have a reliable image quality to demonstrate coronary artery clearly if a reasonable way of scanning is chosen.
