Summary

To Determine whether transcranial ultrasound can detect the presence of intravenously injected microbubbles used routinely for dobutamine stress echocardiography.

Conditions

Interventions

PROCEDURE

Ultrasound on Temporal Bone

All Patients undergoing dobutamine stress echocardiography have an intravenous line placed and a continuous infusion of a commercially available contrast agent administered. Prior to contrast infusion, baseline transcranial ultrasound images at 0.4 mechanical index using low mechanical index pulses and color Doppler will be performed and recorded. After this the contrast infusion will begin, and resting cardiac images will occur.
