      MRI & PET scans will be linked together in a new prototype brain-
      imaging machine that will perform magnetic resonance imaging and
      positron emission tomography at the same time. The new device will
      allow quick and more accurate correlation between activity in various
      areas of the brain and the cellualr level. MRI gives info about brain
      structure and bloof flow to brain regions. PET allows the monitoring of
      metabolic activity at the neuronal/cellular level. The PET/MRI imager
      by Siemens corporation will provide better studies of Alzheimer's
      disease, amyloid plques and drug effectiveness. antidepressants will
      also be studied to see how they impact the brain's activities over time
      in various regions. Receptors can be monitored while simultaneously
      monitoring bloodflow. Studies of bipolar disorder are also planned.
      Several prototypes are being sent out. The first commerical devices
      will be availbale in 18 months.
