The book series Advances in Neurotraumatology, edited by the Neurotraumatology Committee of the World Federation of Neurosurgical Societies, described in the preceding Volume I the traumatic extracerebral collections and in Volume II the cervico-spinal injuries. Volume III deals in depth with the biomechanical, neuropathological and clinical pictures of traumatic lesions of the brain tissue itself, the most frequent consequences of severe head injuries. Experts in the field discuss the new results of their own clinical investigations, neuroimaging and electrophysiology on the interpretation of diffuse and focal dynamic development of supra- and infratentorial cerebral contusions, lacerations and hematomas. Above all they consider the important consequences of these aspects for individual treatment and prognosis. For practical purposes the detailed discussions of each clinical chapter are summarized in instructions for the daily practice.

Magnetic resonance imaging (MRI) is a new and still rapidly developing imaging technique which requires a new approach to image interpreta tion. Radiologists are compelled to translate their experience accumulat ed from X-ray techniques into the language of MRI, and likewise stu dents of radiology and interested clinicians need special training in both languages. Out of this necessity emerged the concept of this book as a manual on the application and evaluation of proton MRI for the radiolo gist and as a guide for the referring physician who wants to learn about the diagnostic value of MRI in specific conditions. After a short section on the basic principles of MRI, the contrast mechanisms of present-day imaging techniques, knowledge of which is essential for the analysis of relaxation times, are described in greater de tail. This is followed by a demonstration of functional neuroanatomy us ing three-dimensional view of MR images and a synopsis of frequent neurological symptoms and their topographic correlations, which will fa cilitate examination strategy with respect to both accurate diagnosis and economy.

The acute abdomen is one of the most frequent, most dangerous and most difficult problems that the diagnostic radiologist has to deal with. This comprehensive manual presents a clinico-radiologic approach to the use of diagnostic imaging techniques for acute abdominal conditions. Imaging techniques, radiologic symptoms and clinical conditions are treated separately. This lucid format, together with a detailed subject index, offer the reader a quick and reliable reference aid in daily practice. The text is clearly structured and concise in style, and provides helpful practical hints, including discussion of diagnostic pitfalls. It is supported by a wealth of illustrations covering native diagnosis, ultrasonography, computer tomography and angiography.

On the eve of the theory's 100th birthday, here is the first complete biography of Einstein's theory of general relativity, revealing the personal feuds and ideological battles, the decades of neglect, the resurgence, and now, the deep questioning of a theory that has given us black holes, dark energy, and modern cosmology.

A presentation of general relativity as a scheme for describing the gravitational field and the equations it obeys. Starting from physical motivations, curved co-ordinates are introduced, and then the notion of an affine connection field is added. At a later step, the metric field is added.
