The CT scan is widely available in most hospitals and is an important tool to differentiate between ischemic strokes and hemorrhagic stroke. It is the most common tool used to diagnose a stroke. An MRI is contraindicated in clients with metal implants or pacemakers, and it can exacerbate claustrophobia. An EEG will determine the presence of brain waves, and it is not a diagnostic test for a stroke. A PET scan determines brain tissue functioning but, it will not be able to differentiate between the types of strokes.
