HEAD SHOTS: Four slices of researcher Vadim Zotev’s head are the first medical images made with low-magnetic-field MRI.
/>Researchers at Los Alamos National Laboratory have made what they say are the first images of a human brain using magnetic fields a hundred-thousandth the strength of conventional magnetic resonance imaging (MRI), paving the way for lower cost medical images that might be better at detecting tumors.
Though the resolution is much lower than that in conventional MRIs, the images “show we have a potential for pretty good results,” says Vadim Zotev, a researcher in Los Alamos’s applied modern physics group. (That’s his head in the images.)

Laser Light for Stroke Treatment
PhotoThera, a company out of Carlsbad, California, is currently conducting clinical trials of their experimental laser system for the treatment of strokes. Using a near-infrared laser that is capable of reaching the brain through the scalp, it is thought that the light can help reinvigorate cells in the ischemic milieu.
To prevent Quire’s [Linda Quire, stroke patient at University of Wisconsin Hospital in Madison –ed.] penumbra from going over to the dark side, two things had to occur.
First, the laser treatment would have to work. Although animal studies and limited human research suggest it might be effective, the treatment still is in the experimental stage and its value has yet to be proved.
Second, Quire would have to get the actual laser treatment. Under the protocol of the clinical trial, half the patients get the treatment and half get a sham treatment. Neither the doctor nor the patients know who is getting treated.
