What is neuroradiology?

Neuroradiology is a subspecialty of radiology. It focuses on the diagnosis of abnormalities of the central and peripheral nervous system, spine, and head and neck using imaging techniques such as CT scans (computed tomography) and MRI (magnetic resonance imaging).

What is neuroradiology used for?

Neuroradiology techniques are used to diagnose a number of conditions that affect the nervous system, including:

• Aneurysms
• Arteriovenous malformations (AVMs)
• Carotid cavernous fistulas (CCFs)
• Cerebrovascular stenosis
• Spinal Malformations
• Stroke
• Vascular tumours
• Vasospasm

What does neuroradiology involve?

Neuroradiology involves using imaging techniques to diagnose conditions affecting the nervous system, including the spine, brain, and nerves. It might also be used to help in interventions by guiding surgeons to the site of the problem they need to treat.

Techniques used in neuroradiology include:

• Magnetic resonance imaging (MRI) scans – magnetic and radio waves are used to create images of inside the patient.
• Computed tomography (CT) scans – these produce detailed cross-sectional and 3D images by using X-rays.
• Angiograms – a contrast dye is injected into the groin. This dye shows up on scans, allowing doctors to look at blood vessels in greater detail.
• Ultrasound – uses sound waves to create images.

Neuroradiology specialists work closely with neurosurgeons to provide them with the information they need to perform the necessary procedures. Neuroradiology techniques may be used in interventions, such as procedures to treat intracranial aneurysms, arterial malformations, tumours and spinal pathologies.
