Determine the Clinical use of brain imaging in disease management

Clinical use of brain imaging in disease management has also grown, driven by broader availability of scanning devices and novel techniques which have fostered new applications for imaging. For instance, neurologists are increasingly using brain scans to differentiate Alzheimer's disease from other forms of dementia. In a main development, government funded Medicare program now accepts PET scans as a reimbursable adjunct to Alzheimer's diagnosis. Doctors may also use scans to figure out the extent of damage to brain from stroke, head trauma, or multiple sclerosis, to characterize brain tumors, and to guide neurosurgeons operating on the brain.
