Stroke TestsYour medical team will do some tests to figure out the type of stroke you have had and the parts of your brain involved. These tests also help rule out other possible causes of your symptoms, such as a brain tumor or a drug reaction.

  • Computerized Tomography (CT). CT scans (sometimes called CAT scans) look at the brain to check for bleeding.

  • Magnetic Resonance imaging (MRI). MRI scans give a more detailed view of the brain, but can take longer than a CT scan.

  • Carotid ultrasound. This procedure shows narrowing or clotting in your carotid artery (the artery in your neck and head that carries oxygen to the brain). A wand-like device (transducer) painlessly sends high-frequency sound waves into your neck. The sound waves create on-screen images.

  • Echocardiogram. This ultrasound technology makes images of your heart so your doctor can see if a clot from your heart has traveled to your brain and caused your stroke.
