    Are you concerned if you have coronary artery disease?

    We are seeking subjects with suspected or known coronary artery disease

We are interested in identifying areas of the heart affected by coronary artery disease (CAD) without the use of any imaging contrast agent. Our study will be looking at the effect of exercise on the heart and blood vessels using cardiac magnetic resonance imaging (CMR).

Study Overview

Participation in our study involves a one-time visit to our center. When you arrive, we will review the MRI safety form, scan procedure, informed consent form, and have you fill out a research payment form. We will then have you change into a hospital gown and pants. Please remember to bring shoes without metal to pedal the bike. In the scanning room, ECG monitoring leads will be placed on your chest. We will also place disposable foam ear plugs in your ears and you will have a headset for communicating with our staff and listening to music. The table will then slide you into the magnet. We will remain in communication with you at all times and continuously monitor your heart rhythm. We will do preliminary scans for approximately 20 minutes, and then slide you out. You will then pedal a bike while lying on the table for approximately 5-10 minutes at increasing resistance to raise your heart rate. Once your heart rate is within the target, we quickly get your feet off the pedals and slide you back in the scanner for the remainder of the scans for 10 min.

* There is no IV or contrast administration involved in this study.

Am I eligible to participate?

You may be eligible to participate in this study if you have known or suspected coronary artery disease (CAD).

You are NOT eligible for this study if:
-You have a pacemaker or a defibrillator
-You are claustrophobic
-You are unable to lie flat

What is the time commitment?

The total scan time is approximately 30 minutes, with 10 minutes of exercise biking while lying on your back on the scan table but outside of the scanner. We book Monday through Friday in 2 hour appointment slots to allow sufficient time for reviewing paperwork.
