Reduced iodinated contrast volume and radiation dose in the new protocol for ct coronary angiography using dual-source imaging with low tube voltage compared with the conventional protocol

To assess the effectiveness and utility of a low-contrastvolume, coronary computed tomography angiography (CCTA) protocol that leverages a lower tube peak voltage (80 kVp) compared to the conventionally employed 120 kVp in patients referred for diagnostic coronary CT angiography.
