Computed Tomography (CT) Scan
Figure 1 Image produced by a CT
CT scan uses x-rays to produce cross-sectional images of the body. It helps to detect
brain aneurysms (bulge or balloon in the blood vessel),
arteriovenous malformations (abnormal tangle of blood vessels), bleeding in the brain,
spine and spinal diseases.

Magnetic Resonance Imaging (MRI)

MRI is a non-invasive medical imaging test that uses magnetic fields and radiofrequency waves to see inside the body. It is used to detect
brain tumours, traumatic head injury, developmental anomalies, multiple sclerosis,
brain aneurysms and
The Department has scanners of varying magnetic strength, from a 1.5 Telsa whole body system suitable for children to a 3.0 Telsa whole body system for faster and more detailed imaging.
here for more information and what to expect during the MRI procedure.
Catheter Angiography (CA)

A CA is a minimally-invasive test that uses x-rays and a contrast material to produce pictures of blood vessels in the brain and spine for diagnosis and treatment. A contrast is a special dye that is injected into veins on the arms or hands to improve the image quality and aid diagnosis.
A CA helps detect brain aneurysms, outline blood vessel malformations, investigate diseases of the vessels and provide additional information on abnormalities seen in MRI or CT scans.
here for more information and tips.
In some cases, procedures may be needed to treat conditions detected by a catheter angiography.
