We are in the midst of major advances in medical imaging, converting static pre sentation of anatomic information into near real-time interactive imaging and displays capable of depicting both structure and function. This will have pro found impact on diagnosis and image-guided therapies. These advances have been most notable in the modalities of computed tomog raphy and magnetic resonance. These technologies have become capable of ac quiring volumetric images in short periods of time. Speed gains in MRI were very significant in the early 1990s with the development of clinically usable pulse se quences for gradient-recalled and echo-planar imaging. It appears that further speed gains in MRI will be difficult to achieve. The development of spiral CT has ushered in an era in which major speed gains in CT are also possible. This has enabled creation of new types of applica tions such as CT angiography, which has already come to replace catheter angio graphy at many medical centers throughout the world. We are very pleased that the results from industrial and academic laboratories have been transferred to the bedside to improve patient care at a speed that may be faster than in any other area of medicine. Concurrent with advances in CT technology there have been dramatic strides in the performance characteristics and costs of computer hardware and software.

This concise integrated handbook looks at all available imaging methods for head and neck cancer, highlighting the strengths and weaknesses of each method. The information is provided in a clinical context and will guide radiologists as to the information the clinician actually needs when managing a patient with head and neck cancer. It will also provide the clinician with the advantages and limitations of imaging. The text therefore deals with Ultrasound, CT and MRI. The initial chapters aim to give the reader a core knowledge, which can be used in imaging by the various methods described. The subsequent chapters are directed towards clinical problems and deal with the common cancers in a logical order.

This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.

The fourth edition of this well-received book offers a comprehensive update on recent developments and trends in the clinical and scientific applications of multislice computed tomography. Following an initial section on the most significant current technical aspects and issues, detailed information is provided on a comprehensive range of diagnostic applications. Imaging of the head and neck, the cardiovascular system, the abdomen, and the lungs is covered in depth, describing the application of multislice CT in a variety of tumors and other pathologies. Emerging fields such as pediatric imaging and CT-guided interventions are fully addressed, and emergency CT is also covered. Radiation exposure, dual-energy imaging, contrast enhancement, image postprocessing, CT perfusion imaging, and CT angiography all receive close attention. The new edition has been comprehensively revised and complemented by contributions from highly experienced and well-known authors who offer diverse perspectives, highlighting the possibilities offered by the most modern multidetector CT systems. This book will be particularly useful for general users of CT systems who wish to upgrade and enhance not only their machines but also their knowledge.

With the contribution from more than one hundred CNS neurotrauma experts, this book provides a comprehensive and up-to-date account on the latest developments in the area of neurotrauma including biomarker studies, experimental models, diagnostic methods, and neurotherapeutic intervention strategies in brain injury research. It discusses neurotrauma mechanisms, biomarker discovery, and neurocognitive and neurobehavioral deficits. Also included are medical interventions and recent neurotherapeutics used in the area of brain injury that have been translated to the area of rehabilitation research. In addition, a section is devoted to models of milder CNS injury, including sports injuries.

This book considers in depth all the factors that influence the radiation dose and the risk associated with MDCT in children and adults. Only a small proportion of referring clinicians, radiologists, and technologists are aware of both the radiation risks and their underlying mechanisms. The book proposes detailed guidelines for optimization of the radiation dose when using MDCT. It is written by experts of international standing.

This book describes current examination techniques and advanced clinical applications of state-of-the-art multidetector computed tomography (MDCT) scanners. There are contributions from several distinguished radiologists and clinicians. Each chapter is written from a practical perspective, so that radiologists, residents, medical physicists, and radiology technologists can obtain relevant information about MDCT applications.
