Magnetic Resonance Imaging In Diseases Of The Nervous System

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 thoroughly updated second edition of this user-friendly resource presents over 1200 carefully selected cases to examine the entire spectrum of CNS diseases of the head and spine, including recently recognized disorders such as posterior reversible edema syndrome, spinal cord herniation, and dysembryoplastic neuroepithelial tumor. Over 1350 illustrations of neuropathology depict both typical and unusual appearances. Hundreds of cross references link the cases to each other to highlight similarities, distinctions, and variations among conditions. Consistent labeling of images on each page enable quick scanning of individual topics.

Magnetic resonance imaging (MRI) is a scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. This book is a comprehensive guide to the diagnosis and management of neurological infectious diseases using MRI. Divided into four sections, the text begins with an introduction to tropical diseases of the central nervous system, and their epidemiology. The second section provides in depth coverage of the technique of MRI, from the basic principles, to clinical application and more advanced features. The following sections describe use of the technique for both infectious diseases, including tuberculosis, HIV and parasitic diseases; and noninfectious conditions, such as stroke, poisoning and epilepsy. Each chapter features numerous MRI and pathological images and extensive references. Key points Comprehensive guide to diagnosis and management of neurological infectious diseases in tropics using MRI In depth coverage of the technique, from basics to more advanced aspects Covers MRI for both infectious and noninfectious conditions Includes nearly 300 MRI and pathological images

Central nervous system (CNS) infections continue to pose a serious problem in health care even with improved knowledge and treatment. Despite the introduction of newer antimicrobial agents and diagnostic techniques, the morbidity and mortality associated with CNS infections remain high. The morbidity associated with CNS infections may be even more important than the death rate especially in developing countries as neurological sequelae may deprive the survivors of intellect and physical ability, demeaning the quality of life and burdening health resources and social services. MR imaging is an important integral part of the protocol for the management of CNS infections and MR spectroscopy is increasingly being utilized in its management. This work is an attempt to provide a comprehensive review of imaging and spectroscopy of the commonly encountered CNS infections in the clinical practice in developing and developed countries. The first chapter deals with basic physical principles of MR imaging and spectroscopy that will help beginners to understand the technical terms used in subsequent chapters. The remaining 10 chapters deal with clinical, pathological, MR imaging and spectroscopy features and their applications in CNS infections. This will help in giving a comprehensive understanding to readers with a background in clinical, radiological, basic MRI, and neurological sciences. The T2 hypointense lesions are a real diagnostic dilemma especially in developing countries for which an algorithm has been suggested in the concluding chapter.

In recent decades, the use of neuroimaging techniques has resulted in outstanding progress in the diagnosis and management of neurological diseases, and this is particularly true of those diseases that affect the white matter of the brain and spinal cord. This book, written by internationally acclaimed experts, comprises a series of comprehensive and up-to-date reviews on the use of MR imaging in these major neurological conditions. The diverse available MR techniques, such as magnetization transfer MRI, diffusion-weighted MRI, MR spectroscopy, functional MRI, cell-specific MRI, perfusion MRI, and microscopic imaging with ultra-high field MRI, offer an extraordinarily powerful means of gaining fundamental in vivo insights into disease processes. The strengths and weaknesses of all these techniques in the study of multiple sclerosis and other relevant diseases are extensively considered. After an introductory section on neuroimaging technology, subsequent sections address disorders of myelination, demyelinating diseases, immune-mediated disorders, and white matter disorders related to aging and other conditions. This book provides a valuable summary of the state of the art in the field, and defines important areas for future research.
