Influence of cardiac function on image quality in coronary computed tomography angiography

To evaluate the correlation between cardiac functional parameters and image quality in coronary computed tomography angiography (CCTA).Sixty-six patients who underwent both CCTA and echocardiography were included. The coronary artery attenuation values and contrast-to-noise ratios (CNR) were measured in the proximal right coronary arteries (RCA) and left main (LM) trunk. Then, the averages of the mean values derived from RCA and LM were...
