... questions. The scientists also conducted magnetic resonance imaging (MRI) to help localize regions on the PET scans. "We saw on our PET scans that the radiotracer 'disappeared' over time as the nicotine receptors became occupied by nicotine from cigarettes," says Dr. Brody.

...story of osteoarthritis. Zhai et al. used magnetic resonance imaging (MRI) to assess bone marrow lesions in the subjects. The authors then calculated the heritability estimates - or the extent to which they are hereditary - for bone marrow lesions in lateral and medial tibia and femur.

... fat in the abdominal region, measured by magnetic resonance imaging, was reduced by 20 percent among exercisers. The group that was not exercising had either no or significantly less improvement than the exercising group. Special scans, using an X-ray machine, were used to assess total body fat.

...k said. The researchers used functional magnetic resonance imaging (fMRI) to examine brain activity and function, a technique that uses magnetic fields to spot active brain areas by telltale increases in blood oxygen.
