The imaging agent is a tantalum oxide nanoparticle, which is inexpensive, and stays in the body long enough to image many different organs.

The images produced in one of the world's most powerful MRI (magnetic resonance imaging) systems whose power is equivalent to 150,000 times Earth's magnetic field are of a much higher detail than cardiac images commonly generated in current clinical practice. The ultra-high field approach permits a superb delineation between blood and heart muscle. Even subtle anatomical structures are made clearly visible. The new procedure holds the promise to advance the capabilities of cardiac research and care as cardiac malfunctions can be diagnosed, treated and monitored at a much earlier point in disease progression.

Researchers have now set out to change that.
