Investigations are used to confirm the diagnosis of stroke and find out the possible causes so that we can address these and hopefully prevent a recurrence. Common investigations undertaken in stroke patients include the following:

CT scan uses X-rays to image your brain. This helps to tell us the type of stroke and the area of the brain affected. The scan is painless and only takes a few minutes while you move through a ring-like scanner.

MRI scan uses magnetism to provide very detailed pictures of the brain. The scanner is shaped like a tube and you lie on a bed which travels into the scanner. It takes approximately 30 minutes. It is a painless process but some people find it a little noisy and claustrophobic.

Blood tests will be carried out on admission and throughout your stay. These are often done by specialist staff called Phlebotomists.

Electrocardiogram (ECG) records the rhythm of the heart. Sensors are placed on your chest during this painless procedure.

Echocardiogram (ECHO) uses ultrasound to give a detailed picture of the heart by passing a sensor over the chest. A clear jelly is applied to the probe to aid contact with the skin.

Carotid Doppler Scan is an ultrasound scan that detects any narrowing of the carotid arteries in your neck which can contribute to stroke. Like the echocardiogram, it uses sound waves and is non invasive.
