Methods A total of 70 patients (30 men,40 women;mean age [49. 89 ± 10. 85]years) were selectedin this analysis. These patients were examined byMSCT with suspected coronary heart disease,and MSCTresults showed no coronary artery disease ( no coronaryartery deformity,variation,right dominant type of coronaryartery) and no other heart disease in these patients.Systolic phase (45%) and diastolic phase image (75%)of the original image were reconstructed,and coronary sinus,mainly branch diameter,sectional area were quantitativelymeasured to analyze the relationship between theabove imaging indexes with the different phase of cardiaccycle.展开更多
