This book provides the essential information needed for formulating findings in CT of the head and spine. The book is conceived as a highly practical guide for use in routine CT diagnosis, as well as in critical on-call emergency situations. The features: * Condenses information to the core questions of the diagnostic problem at hand without oversimplifying: What does the clinician want to know? What must be included in the findings, and what differential diagnosis must be excluded? * Clear and didactic organization of information in pathogenesis, clinical findings, and CT morphology * Convenient summaries, offset by a second color, provide information to be used during the CT examination that assure that nothing will be overlooked * Detailed descriptions of normal anatomy with normal values help to differentiate pathologic from normal findings.
