If you are suspected of having a stroke, you will be assessed urgently at the Emergency Department.
You will have a Computed Tomography (CT) scan to identify the type of stroke, the location and its severity. Blood tests will also be done to help evaluate other causes of your symptoms and guide treatment, e.g. blood sugar levels, cholesterol and how quickly the blood clots.
Some patients may require additional tests to identify the cause of the stroke or to assist with treatment, for example:
1. Angiogram
An angiogram is an advanced x-ray of the blood vessels. It is done by inserting a small flexible tube through the blood vessels up to the brain. Dye is then delivered into the blood vessels of the brain, making them visible on the X-ray for easier identification of the location and severity of the stroke.
2. Electrocardiogram (ECG)
An electrocardiogram (ECG) records the electrical activity in the heart. It can detect underlying heart conditions that may have led to the stroke, such as previous heart attacks or irregular heartbeats (arrhythmia).
3. Carotid ultrasound
The carotid arteries are located on either side of the neck and supply the brain with oxygen and nutrients. A carotid ultrasound uses sound waves to assess the blood flow in the neck and check for narrowing or blockages in the carotid arteries.
