- W2359544083 abstract "Objective To investigate the reason and strategy of artifact of coronary artery imaging with 64-slice spiral CT.Methods 1000 patients with diagnostic or suspected coronary artery disease underwent retrospectively ECG-gated 64-slice spiral CT. Images were reconstructed under different reformations of MPR, MIP and VRT. Image quality was assessed by two experienced radiologist. Results A total 13470 of 15000(89.80%) segments were visualized,the artifact segments were 1920,the incidence was 14.25%,the incidence of lower grade artifact was 13.65%, medium and heavy incidence added up to 0.60%. Breath movement caused most artifact,the other reason was heart rate. Conclusion The reason of artifact includes:breath,speed of heart, rhythm of heart, contrast concentration,rebuild percent and so on. Hold-breath and inhibit irregularity heart rhythmn,low-heart-rate,more rebuild percent lead to accurate diagnosis." @default.
