Traumatic brain injury is a leading cause of death and disability in the United States. The mortality and morbidity associated with traumatic brain injury have declined. Improved patient outcomes have resulted from improvements in emergency department diagnosis which leads to effective emergent treatment. CT is usually the initial imaging study performed on apatient with traumaticbrain injury. Medical imaging helps to deﬁne the acute injury and, if necessary, to guide acute surgical intervention. It has also contributed to our understanding of the nature and pathophysiology of these injuries.
Overall, the use of CT in the emergency department increased more than threefold between 1996 and 2007; however when adjustments are made for variables such as severityof injurythere maybe little change in the utilization rate of cranial CT. Increased CTusage has likelyresulted from the increased 24 hour availabilityof CTin emergency departments. Along with the increased use of emergent CT, has come a greater emphasis on accurate and rapid imaging interpretation. The role of the radiologist has become much more central to the health care delivery team. Radiologists who maynot be specialtytrained in emergencyimagingor in neuroimagingare being increasingly called upon to provide a high level of contemporaneous imaging interpretation. The need to provide coordinated imaging assessment to the emergency department patient has never been greater. This book is an important and timely contribution to the ﬁeld.
It is noteworthythat Dr. Anzai and Dr. Fink have compiled the latest information on traumatic brain injury in comprehensive volume. Both these neuroradiologists are well known for their many important contributions to the imaging literature. They have also included contributions from authors who have extensive experience in the imaging of traumatic brain injury.
The authors and their collaborators do not conﬁne themselves to the imaging aspects of traumatic brain injury. Epidemiology and decision rules are discussed in separate chapters. The special considerations of pediatric head trauma are explored. Outside the brain, but vital to the comprehensive care of the brain injured patient, are chapters detailing cerebrovascular injuries, skull base injuries, maxillofacial injuries, and orbital injuries. It is appropriate that the book concludes with a chapter about advanced imaging. Magnetic resonance techniques including diffusion tensor imaging, spectroscopy, susceptibilityimaging, and functional imaging are illustrated. There are also brief discussions of magnetoencephalographyand positron emission tomography. These advanced techniques have deepened our understanding of traumatic brain injuryin selected patient cohorts. This chapter mayserve as a preview to the next clinicallyrelevant new imaging techniques to be applied to the care of traumatic brain injuries.
This book provides the radiologist with an important resource for the interpretation of images of the brain, face, and neckof the brain injured patient. To the clinician caring for the brain injured patient, it provides helpful guidelinesfor the ordering of imaging studies and insight into how the pathophysiology of injury is depicted by imaging. Those researchers studyingtraumatic brain injurywill gain a better understanding of how the application of imaging guides therapy. To all the imagers, clinicians, and researchers interested in neurotrauma, Ihope that you will enjoyhaving such a valuable resource.
