How do doctors rule out strokes?

A brain CT scan can show if there is bleeding in the brain or damage to the brain cells from a stroke. Magnetic resonance imaging (MRI) uses magnets and radio waves to create pictures of your brain. An MRI may be used instead of—or in addition to—a CT scan to diagnose a stroke.

Does your blood pressure go up with a stroke?
