Preface
Why do we need a book on the dating of neurological injury? Over the last decade, I have personally reviewed more than 80 medical–legal cases related to neurological disease in which some aspect of the case involved imaging technology. Many cases – in clinical situations, such as alleged birthrelated hypoxia or ischemia, surgically-related injuries, or trauma-induced spinal cord or brain substance abnormalities, for example – shared the need both to detect the presence of an injury and to date the time it occurred. While a minority of cases involved the misdiagnosis of an aneurysm, a delayed diagnosis of spinal fracture, or orbital injury during a surgical procedure, the large majority of cases used modern imaging, first to detect if an injury had occurred to the brain substance or the spinal cord (collectively referred to as the central nervous system) and second to determine, if an injury did occur, at what time it occurred. In a medical–legal setting, the interplay between the radiographic findings and the clinical findings has several possible scenarios. On one extreme, the imaging findings may be so unequivocal that no doubt exists as to what occurred and even little doubt about when it occurred. On the opposite extreme, the radiologic findings may be either completely n
