Clinical Neuroradiology

Description

A truly interdisciplinary clinical text, Clinical Neuroradiology investigates the structure-function relationship for major CNS diseases, illustrated by considering actual clinical cases. Authored by a leading neuroradiologist, this landmark publication provides neuroradiologists with clinical neurological correlates and neurologists with imaging correlates for all key neurological conditions. Organised by brain region, each chapter contains an introductory section of clinically relevant neuroanatomy followed by a series of case studies giving: • Brief history and summary of findings • Differential diagnosis • Imaging findings, related to clinical deficits • Pertinent neuronal circuits, neurochemistry and neurogenetics • Basic therapeutic approaches to each syndrome Due to its utility in demonstrating structural-functional correlates, a separate chapter on stroke is included. Lavishly illustrated with images from all modalities and outstanding anatomical diagrams rendered in true radiographic (rather than 'upside-down' anatomic) orientation, Clinical Neuroradiology is an invaluable resource for everyone involved in the diagnosis and management of neurological disorders.
