Clinical Trial Summary

To detect coronary artery disease by both coronary and carotid artery imaging and myocardial perfusion imaging using a new low mechanical index real time system.

Description:

The objective of this clinical study will be to visualize both coronary and carotid arteries as well as detect myocardial perfusion following a routine intravenous injection of Definity (0.05-0.20 millimeters), Optison (0.1-0.4 millimeters) or PESDA (0.05-0.2 mL). Following these injections , we will attempt to Contrast Pulse Sequencing on the Siemens Acuson Sequoia system to image both the coronary and carotid arteries, as well as the Myocardial perfusion.
