Neuroradiology

Neuroradiology is a subspecialty of radiology focusing on the diagnosis and characterization of abnormalities of the central nervous system, spine, and head and neck using neuroimaging techniques.

Overview

Neuroradiologists are physicians who specialize in diagnosing and treating diseases and injuries of the brain, spine, and nervous system using medical imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), and angiography.

Techniques

Computed Tomography

Computed tomography (CT) is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce detailed images of any part of the body, including the bones, muscles, fat, organs, and blood vessels.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive, usually painless medical test that helps physicians diagnose and treat medical conditions. MR imaging uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures.

Angiography

Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers.

Diseases and Conditions

Neuroradiology plays a key role in diagnosing a wide range of conditions, including brain tumors, stroke, aneurysms, Alzheimer's disease, and multiple sclerosis.
