Brain scans

  • Computerised tomography (CT scan) or magnetic resonance imaging (MRI) take detailed pictures of your brain.
  • After a suspected stroke, everyone should have a brain scan.
  • Doctors determine if you have had a stroke by looking at the scan.
  • The scan shows which part of your brain was injured and how badly.

Imaging of the arteries

Ultrasound, CT angiogram or MRI show how the blood flows through the arteries.  

Heart tests

  • An electrocardiogram (ECG) tests for abnormal heart rhythm.
  • You may also need to wear a Holter monitor for 24 hours or longer.
  • Your doctor may also order an echocardiogram.  

Blood tests

You may need cholesterol (fasting lipids), blood sugar levels, and tests to see how well your kidneys work and the way your blood clots.  

Blood pressure check

After an initial check of your blood pressure, you will need it checked regularly.

Your doctor will discuss your test results with you. They will make a plan for follow up. It is important to go to any appointments arranged by your doctor.
