Feasibility of Low-volume Injections of Contrast Material with a Body Weight-Adapted Iodine-Dose Protocol in 320-Detector Row Coronary CT Angiography

The use of 0.7 mL/kg of contrast material injected at a fixed duration of 10 seconds was feasible for CTCA using 320-detector row CT, with a sufficient and reliable contrast enhancement in the ascending aorta and coronary artery.
