OBJECTIVE. The purpose of our study was to review investigations that evaluated contrast infusion using MDCT with submillimeter detector configuration for coronary artery CT angiography (CTA). Published data-are supplemented with 2006 survey results from centers practicing 64-MDCT coronary artery angiography.

CONCLUSION. Literature and survey results suggest a consensus for the use of IV contrast volumes < 100 mL, infusion rate of 5 mL/s, and a saline chaser. A range of concentrations can be used to attain target coronary artery attenuation levels.
