Dual-step prospective ECG-triggered 128-slice dual-source CT for evaluation of coronary arteries and cardiac function without heart rate control: a technical note

Purpose To describe prospective ECG-triggered dual-source CT dual-step pulsing (pECG dual_step ) for evaluation of coronary arteries and cardiac function. Methods Fifty-one consecutive patients pre- or post-cardiovascular surgery were examined with adaptive sequential tube current modulated (pECG du...
