Magnetic Resonance Imaging (MRI)

This image combines pre- and post-treatment scans from the same patient. Analysis of the two scans revealed that the area and size of post-treatment bleeding corresponded to blood-brain barrier disruption (shown in green, yellow and red) prior to therapy. Image courtesy of Richard Leigh, NINDS.

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.
