The development of ultra-high-resolution CT (U-HRCT) is expected to improve the accuracy of coronary stenosis evaluation. This study aimed to evaluate the accuracy of the stenosis severities of coronary artery phantoms estimated using U-HRCT by comparing them to those estimated with conventional CT. Coronary artery phantoms with non-calcified and calcified lesions were scanned with conventional CT (64-row×0.625mm) and U-HRCT (32-row×0.3125mm). The coronary artery phantoms had lumen diameters of 2.0, 3.0, and 4.0mm with non-calcified l
