How is a Stroke Diagnosed?

Diagnosis of a stroke relies on the patient’s medical history and certain tests. These may include:

Magnetic resonance angiography (MRA) scan to show the flow of blood through the blood vessels
Carotid arteriography to show specific arteries
Other laboratory tests may also be done to check the patient's overall health and whether the blood clots too easily
If evidence shows that the stroke is caused by a clot that formed in the heart, the doctor may order a chest X-ray, ECG or EKG, echocardiograph or other heart imaging test
