Interpretation of Emergency Head CT

Description

Interpretation of Emergency Head CT is an invaluable quick reference to the key aspects of the head CT. It provides the clinician with an easy-to-use 'ABCs' system to analyse any head CT scan that may be encountered in the acute setting. Section 1 contains both a comprehensive section on radiological anatomy of the brain showing cranial anatomy overlaid onto CT images and technical details of CT imaging in a simplified form. Section 2 covers the wide gamut of conditions that are likely to be encountered in acute medical practice. Pitfalls are highlighted and tips are included to assist the recognition of important signs, along with ways to distinguish other pathologies with a similar appearance. This is an excellent practical resource for all clinicians who utilise CT scans of the head as part of their patient management.
