This book with CD-ROM includes a case collection of 25 hyperacute stroke patients, all imaged within six hours of stroke onset with a complete stroke MRI protocol. Stroke MRI and the established clinical methods are compared and recent results from single and multicenter trials are presented to demonstrate the advantages of MRI for stroke-patients. The book and CD will be useful to both the experienced researcher using MRI and the clinician or researcher with no previous knowledge of the technology.
