A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

New insights into brain cell metabolism from PET and MRI scans

By discovering a crucial piece of submicroscopic information about how the brain converts fuel into energy for neurons, Cornell University biophysicists have gleaned new insights into brain cell metabolism that will allow neurologists to better interpret data from such diagnostic tests as positron emission tomography (PET) scans and a specialized magnetic resonance imaging (MRI) test.
