Neuroradiology
Neuroradiologists specialize in evaluating the various disorders of the central nervous system, including the brain, head and neck regions, and spine. Primarily using the powerful cross-sectional techniques of magnetic resonance imaging (MRI) and computed tomography (CT scan), they also perform contrast myelography and image directed therapeutic injections in the spine. Angiography is used to diagnose vascular lesions of the central nervous system, which in some instances may be treated by catheter directed techniques.
Interventional neuroradiology or endovascular surgical neuroradiology is a subspecialty of neuroradiology that utilizes catheter directed, minimally invasive techniques to occlude aneurysms, arteriovenous malformations and tumors in the brain, neck and spine. Endovascular catheter directed techniques can also be used to treat acute stroke with clot removing catheters and intra-arterial administration of clot dissolving medication, often reversing stroke symptoms. Arterial stenosis in the arteries of the neck and brain can be treated using stents and drug eluting stents.
