IV contrast infusion for coronary artery CT angiography: Literature review and results of a nationwide survey

Research output: Contribution to journalArticlepeer-review

Abstract

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.
