Magnetic Resonance Imaging (MRI)

MRI creates images from the magnetic resonance created in hydrogen atoms when they are polarized and an electromagnetic pulse is used to knock them off axis. This section includes MR analysis software, MRI scanners, gadolinium contrast agents and related magnetic resonance imaging 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.

concussion outcomes, MRI, DTI, diffusion tensor imaging, Albert Einstein College of Medicine, Montefiore

This image of a concussion patient's brain shows low FA areas (red) probably signifying injured white matter, plus high FA areas (blue) perhaps indicating more efficient white-matter connections compensating for concussion damage. A large amount of high FA predicts recovery from concussion. Image courtesy of PRNewsFoto/Albert Einstein College of Med.

This High Angular Resolution Diffusion Image (HARDI) of the human brain shows long distance connections, or tracts, grouped on the basis of their anatomical neighborhood. Wiring associated with particular brain structures share the same color. In diffusion imaging, the scanner detects movement of water inside neural fibers to reveal their locations.Anastasia Yendiki, Ph.D., Viviana Siless, Ph.D., MGH/Harvard, Boston Adolescent Neuroimaging of Depression and Anxiety (BANDA)
