What is Neuroradiology and who are neuroradiologistsNeuroradiology is the medical subspecialty that deals with the diagnosis and treatment of brain, spinal cord, head and neck, and vascular lesions using x-rays, magnetic fields, radio waves, and ultrasound. These forms of energy are harnessed with machines such as the CT (CAT) scanner, magnetic resonance (MR) scanner, and ultrasound machines. Additionally, angiography is also a tool of the neuroradiologist. This is performed by inserting a small tube, known as a catheter, into the arteries that supply the brain and spinal cord with blood. Through this tube, compounds that identify blood vessels or that treat selected blood vessel or soft tissue diseases can be placed. Neuroradiologists are physicians who have specialized in the field of radiology. Following medical school, their training, known as residency, entails four rigorous years of supervised practice using these tools. Following radiology residency, the neuroradiologist undergoes two additional years of fellowship training under the supervision of trained neuroradiologists. Certification for practice includes the board examinations in radiology. This examination includes a two-day written examination followed by a day of oral examinations. Neuroradiology has an additional certification known as a certificate of added qualification, which entails a day-long oral test. The Washington University neuroradiologists are board-certified.
