TL;DRAbstract

This is an initial report on the use of the recently introduced whole-heart 320-slice computed tomography (CT) scanner for noninvasive coronary angiography compared with conventional coronary angiography (CCA). Whole-heart CT avoids overscanning and overranging as necessary for helical coronary CT acquisitions thereby significantly reducing the effective radiation dose. Twelve patients with suspected coronary artery disease (4 women, 8 men; mean age 64.6 ± 11 years) have undergone coronary CT angiography using a 320-slice scanner (Aquilion ONE, Toshiba; 0.35 s gantry rotation time, 120 kV, and 350 – 450 mA) prior to clinically indicated CCA. CT images were manually reconstructed in motion-free phases with 0.5-mm slice thickness and 0.25-mm slice increment. Independent blinded assessment of CT and CCA (using quantitative analysis) was performed to detect significant (at least 50%) diameter stenoses. Of the 12 patients, in 8 patients, single-heart beat CT acquisition was performed, resul
