Magnetic Resonance Imaging (MRI)

Cardiac MRI creates images from the resonance of hydrogen atoms when they are polarized to face in one direction and then hit with an electromagnetic pulse to knock them off axis. The wobbling of the atoms is what is recorded by computers and used to reconstruct the images. Cardiac MR allows very detailed visualization of the myocardial tissue above the resolution found with cardiac CT. Using different protocol sequences, various contrast type images can be created with MRI to enhance various tissues or to provide physiological data on the function of the heart. This section includes MR analysis software, MRI scanners, gadolinium contrast agents, and related magnetic resonance accessories.

BHF, Reflections of Research image competition, U.K., 4-D MRI, heart blood flow

This image shows blood flow within the main pumping chambers – the ventricles – on both sides of the heart and the vessels leaving the heart. The blue flow is blood that needs oxygen and is travelling to the lungs. The red flow is blood that has been through the lungs and received oxygen. Victoria Stoll of the University of Oxford is using this type of imaging to look at the blood flow within the hearts of people with heart failure, whose hearts are not pumping effectively.

Duke scientists have discovered a new class of inexpensive and long-lived molecular tags that enhance MRI signals by 10,000-fold. To activate the tags, the researchers mix them with a newly developed catalyst (center) and a special form of hydrogen (gray), converting them into long-lived magnetic resonance 'lightbulbs' that might be used to track disease metabolism in real time.
