The Department of Neuroradiology at the National Neuroscience Institute (NNI), provides subspecialised services to inpatients, outpatients, and referrals from private healthcare providers.

The Department is equipped with a range of neuro-imaging equipment, to produce images of the brain and spine for diagnosis.

The services include:

The Department also uses a Picture Archiving and Communications system (PACS) to store radiological and imaging data. This system enables quick retrieval of imaging data and enable quick reports for diagnosis and comparison.


Computed Tomography (CT) Scan

CT scan uses x-rays to produce cross-sectional images of the body. It helps to detect strokes, brain aneurysms (bulge or balloon in the blood vessel), arteriovenous malformations (abnormal tangle of blood vessels), bleeding in the brain, head injuries, dementia, and 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, stroke, dementia, infections, brain aneurysms and arteriovenous malformations.

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.

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.

Interventional Neuroradiology

In some cases, procedures may be needed to treat conditions detected by a catheter angiography.

  • Embolisation
    • Treat the brain aneurysm, or close the aneurysm sac by filling it with a material (coil stent) to reduce the risk of bleeding
    • Block abnormal blood vessels
    • Reduce blood supply in brain tumour patients before surgery
  • Endovascular Therapy
    • Remove clots in patients who suffered an acute ischemic stroke
