Neuroradiology

Neuroradiology is a subspecialty of radiology focusing on the diagnosis and characterization of abnormalities of the central and peripheral nervous system, spine, and head and neck using neuroimaging techniques. Primary imaging modalities include computed tomography (CT) and magnetic resonance imaging (MRI). Plain radiography is utilized on a limited basis and ultrasound is used in limited circumstances, in particular in the pediatric population. Angiography is traditionally used for diagnosis of vascular abnormalities or diagnosis and characterization of masses or other lesions but is being replaced in many instances by CT or MRI angiography and imaging.
