Abstract

The temporal characteristics of a gated injection system was investigated in a hydrodynamic flow phantom using time density curves generated from digital subtraction angiographic recordings. After the inherent delay in the injection system was determined, a series of 22 nonselective coronary angiographies were performed in 9 dogs with gated injections. It was found that rapid gated injections during diastole resulted in significantly increased opacification of coronary arteries and image quality compared to continuous and systolic injections. High contrast sensitivity in digital subtraction angiography combined with diastolic contract medium injections will decrease the required contrast medium dose in nonselective coronary angiography.
