Nanoparticles illuminate brain tumors for days under MRI

A research team is demonstrating some of the world's first clinical applications for nanometer-size particles in the brain. The scientists have shown that an iron oxide nanoparticle as small as a virus can outline not only brain tumors under magnetic resonance imaging, but also other lesions in the brain that may otherwise have gone unnoticed, according to a study published in the journal Neuropathology and Applied Neurobiology.From the Oregon Health & Science University :Nanoparticles illuminate brain tumors for days under MRI.
