Magnetic resonance imaging may depict pathological changes before the development of clinical stroke symptoms."...Novel brain areas associated with the recognition of gender, ethnicity and the identity of faces
...ian. The authors then used functional magnetic resonance imaging to measure brain responses using the same paradigm. This allowed them to isolate brain responses driven by very selective neurons tuned for both ethnicity and gender. As expected, they found brain responses to the female Asian and male Caucas...Smoking worsens knee osteoarthritis
... (4 percent). The researchers took MRIs (magnetic resonance images) of the more symptomatic knee of each patient at the study beginning, and also 15 and 30 months later. Cartilage loss over follow-up, based on knee MRIs, was determined at the tibiofemoral joint (the connection between the thighbone and shinb...Changes in brain density can help predict schizophrenia
...The scans were generated using structural magnetic resonance imaging techniques (sMRI). Job et al. analysed changes in grey matter density in the scans, over a period of 18 months. Eight of the individuals studied went on to develop schizophrenia, on average 2.3 years after the brain scans were collected. Jo...The pain from fibromyalgia is real, researchers say
...g two neuroimaging techniques functional magnetic resonance imaging (fMRI) and single photon emission computed tomography (SPECT) indicate there is a difference between patients with and without fibromyalgia. In people without pain, these structures encode pain sensations normally. In people with fibromyalg...MRI shows brains respond better to name brands

This is the first functional magnetic resonance imaging (fMRI) test examining the power of brands, said Christine Born, M.D., radiologist at University Hospital, Ludwig-Maximilians University in Munich, Germany. We found that strong brands activate certain areas of the brain independent of product...Study explores cause of exercise intolerance in heart failure patients

They also had a magnetic resonance imaging (MRI) test to assess blood flow through their femoral artery before and after flow was temporarily stopped with a blood pressure cuff. This test measures small changes in the size of the vessel interior and in blood flow velocity. Patients ...Hormone replacement therapy may improve trip down memory lane

...oxide is a contrast agent used to enhance magnetic resonance imaging, or MRI. "Photofrin goes into tumor blood vessels and collapses the vasculature, which then starves the tumor of the blood flow needed to survive. The problem with free photofrin therapy is that it can cause damage to healthy tissue. In our...High-tech spectroscopy may be used to monitor neuropsychiatric symptoms

All of the alcoholics had long, heavy drinking careers and were still drinking heavily at the time of the study. "...U of MN earns $7.9 million NIH grant to expand neuroscience research
