Breathing-Induced Myocardial Oxygenation Reserve – Pilot Study (B-MORE Pilot)

This project was led by: Christopher J François MD

This project was funded by:

The term of this project was: May 2016 to January 2017

The number of subjects scanned during this project was: 20

The goal of this study is to test a new cardiac (heart) magnetic resonance imaging (MRI) method. The new MRI method can be used to measure the oxygen content in the heart during breathing maneuvers. Participants will be asked to perform breathing maneuvers during a cardiac MRI exam, including breathing at a specific rate, and also holding their breath for certain intervals. The new MRI method will be used to measure the oxygenation level in the heart muscle. This new MRI method might prove to be an easy and non-invasive way to quickly diagnose cardiac problems in patients without requiring them to take drugs during the diagnostic procedure. Participants will be asked to participate if they have been advised by their doctor to undergo a coronary artery angiogram. The MRI will be performed in WIMR during a single visit.
