Neuroradiology is a subspecialty of radiology centered on the diagnosis and characterization of abnormalities of the central and peripheral nervous system, spine, head and neck using neuroimaging techniques. Primary imaging modalities include computed tomography (CT) and magnetic resonance imaging (MRI). Photography is used
Radiography is of limited scope, as well as ultrasound imaging is used in certain circumstances, especially in pediatrics. Angiography (arterial catheterization) is also commonly used to diagnose vascular abnormalities, or to diagnose and characterize masses or other lesions, but is now being replaced in many cases by computed tomography and magnetic resonance imaging.
In the United States, radiologists are required to have studied neuroradiology for at least four months in order to be eligible for Board Radiology certification. The Neuroradiology Scholarship is a one- or two-year program following a major in Diagnostic Radiology. Interventional neuroradiology is another sub-discipline, which requires an additional year or two of training. This field includes endovascular, or minimally invasive, diagnosis and treatment of central nervous system or head and neck lesions such as tumors, aneurysms, vascular malformations, or strokes.
The American Society for Neuroradiology (ASNR) is the primary professional association in the United States representing neuroradiologists. It is published in the American Journal of Neuroradiology (AJNR). It holds an annual meeting in different cities, usually held between late April and early June.
