Abstract

Neuroradiology is an essential tool in management of patients with neurological and neurosurgical disorders. The aim of this chapter will be to acquaint the reader to understand how images are formed on a computed tomography (CT) and magnetic resonance imaging (MRI) along with a review of the relevant neuroanatomy. This understanding will be helpful to the reader in interpretation of images and diagnosis of various neurological disorders.
