NEURORADIOLOGY is a subspecialty of Radiology specializing in the interpretation of medical images of the neurological system including the brain, brainstem, spine, spinal cord, and nerves. Images are typically acquired from MRI, MRA (magnetic resonance angiography), CT, and CTA (computerized tomographic angiography) sequences. Neuroradiologists first complete a full residency in Radiology followed by several years of dedicated fellowship in Neuroradiology or Pediatric Neuroradiology. While the interpretation of neurological imaging is the cornerstone of Neuroradiology, actual patient treatment is the hallmark of Interventional Neuroradiology. Interventional Neuroradiologists (subspecialists in Neuroradiology) utilize advanced imaging and guidance systems to perform complex neurological procedures that were unimaginable (or only performed by Neurosurgeons) just a few years ago. Examples of common Interventional Neuroradiology procedures include coiling of aneurysms and vascular malformations, and the treatment of acute strokes with clot-retrieval devices. Many of these procedures are performed by Endovascular Neurosurgeons as well.
Litigation against Neuroradiologists nearly always alleges misinterpretation of imaging studies. Interventional Neuroradiologists are subject to claims involving procedural complications including bleeding, perforation, and/or damage to adjacent structures. Neuroradiologists are often called as experts to interpret complex MR or CT images of the spine to determine the presence or absence of disease.
