Coronary computed tomography angiography at 140 kV <i>versus</i> 120 kV: assessment of image quality and radiation exposure in overweight and moderately obese patients

Abstract

140 kV CCTA resulted in similar image quality but a higher effective radiation dose in comparison to 120 kV CCTA. Therefore, in overweight and moderately obese patients, a tube potential of 120 kV may be sufficient for CCTA with diagnostic image quality.
