Fall-induced hip fracture is an epidemic health risk among elderly people. This book presents an image-based multilevel modeling approach to understanding the biomechanics involved in fall-induced hip fracture. By hierarchically integrating a body-level dynamics model, a femur-level finite element model, and a local bone failure model, the biomechanics approach is able to simulate all stages in sideways falls and to incorporate all biomechanical variables affecting hip fracture. This book is useful for clinicians to accurately evaluate fracture risk, for biomechanical engineers to virtually test hip protective devices, and for biomedical students to learn image-based biomechanical modeling techniques. This book also covers: Biomechanical viewing on bone composition, bone remodeling, and bone strength Bone imaging and information captured for constructing biomechanical models Bone mechanical testing and mechanical properties required for biomechanical modeling

Dementia is a massive and increasing global problem, with the current prevalence anticipated to double every 20 years as people live longer. Neuroimaging in dementia is recommended by most clinical guidelines and its role has traditionally been to exclude a mass lesion, rather than to support a specific diagnosis. All radiologists will be aware of a steady rise in the number of requests for brain imaging in old people, but what can imaging reliably tell us and what kind of imaging should we use? In affluent societies we now have a range of structural and molecular brain imaging techniques at our disposal, with specific ligands and sophisticated image analysis techniques now available for clinical use. However, we have difficulty justifying which patients to scan, using which modality and when. We know that Alzheimer's disease is the most common neuropathology contributing to a diagnosis of Alzheimer's disease but we also know from large post-mortem studies that most brain pathology in those who have died with a diagnosis of dementia is mixed. Thus understanding different diseases that can cause dementia, how these co-exist or interact and appreciating that not all dementia is Alzheimer's disease is important.? Equally important is awareness of individual differences in response to a neuropathological burden and what factors provide resilience against dementia that might be maximized to reduce or postpone its impact. This issue draws together contributions from experts in their fields to provide clarity to the topic in a comprehensive collection of articles.

An especially important issue during these uncertain times, this collection of articles examines Neuroimaging from an economic perspective, with articles that discuss leadership, "turf battles?, strategic planning in the face of declining reimbursement, and the impact of teleradiology and telemedicine in cutting costs and improving access.?

Imaging in pediatric patients is also discussed.

The practice of Emergency Radiology has undergone rapid change in the last decade: as imaging procedures are increasingly performed within short periods of time after the arrival of patients to the emergency room, the expectation for near real-time interpretations (often by subspecialists) has gained popularity. Larger emergency centers provide 24 hour on-site coverage by well trained radiologists, while others rely on the services of equally well trained radiologists located off-site, taking advantage of modern universal interconnectivity. Either way, radiologists' input is increasingly affecting the immediate outcome of patients presenting with acute symptoms.? Radiologists have embraced the challenge to protect patient safety by seeking evidence-based data to support the proper utilization of CT (including the use of alternative imaging modalities) and radiologists and CT manufacturers together have worked intensely to find optimal methods to deliver the inevitable radiation.

This text evolved as a response to numerous requests to present a simplified approach to the diagnosis and management of most of the common aspects of both cosmetic and medical venous disorders. The authors, representing experienced plebologists from several different primary disciplines, have attempted to present simplistic paradigm-oriented approaches on how to thoughtfully evaluate and manage common vein issues with contemporary solutions. Several areas of phlebology were not addressed in this text. The management of vascular malformations are beyond the scope of this text and were not covered in detail. Although indications for the appropriate use of IVC filters are discussed, the details about the specific devices, their placement and removal are also beyond the scope of this text. Deep venous obstruction from prior thrombosis, venous compression by arteries such as the compression of the left common iliac vein by the right common iliac artery and pelvic venous insufficiency can now be managed with minimally invasive image guided treatments; the technical aspects of such treatments are complex and not discussed in detail in this handbook. This book will increase the therapeutic skill of the practicing phlebologist and thus increase the quality of care for patients faced with problems related to venous disorders.

Accurate interpretation of indications for treatment is the cornerstone of success in medicine. This book carefully examines the relation between clinical features, diagnosis, and choice of minimally invasive technique for a range of spine pathologies. It explains how selection of technique is intimately related to clinical and diagnostic aspects and how recognition of this relation forms the foundation for an optimal outcome. In addition to examining the various minimally invasive options, including the latest techniques, careful attention is paid to the role of medical treatment in avoiding recurrence after initial therapy. Nerve blocks, epidural injections, and intradiscal procedures are among the many options available in the armamentarium of the interventionalist, and advice is given on their use in different contexts. This volume will be of great value for neuroradiologists and others responsible for treating patients with spine disorders.

Diseases once believed to be confined to the tropics, such as parasitic, mycobacterial, fungal, bacterial, and viral infections are still a major cause of mortality and moribidity in the tropics, yet can affect the developed world in an era of increased global travel and migration.

Experts from tropical countries share their experiences regarding tropical disorders, some of which are rare in the western world, but possible to appear in patients and not readily recognized by specialists not familiar with these diseases.

Topics in this issue include: Relevance of neuroimaging in the diagnosis and management of tropical neurologic disorders; Pathology of Tropical Diseases; Viral Infections of the Central Nervous System; Central Nervous System Tuberculosis; Parasitic diseases of nervous system; Neuroimaging in Post-infectious Demyelination and Nutritional Disorders of the Central Nervous System; CNS Fungal Infections in the Tropics; Neuroimaging Epilepsy in the Tropics; Neuroimaging in Cranio-Vertebral Anomalies as seen in Tropics; Vascular Brain Pathologies; Neurobrucellosis; Hirayama Disease; Transverse Myelitis; and Pyomyositis.

Color perception plays an important role in object recognition and scene understanding both for humans and intelligent vision systems. Recent advances in digital color imaging and computer hardware technology have led to an explosion in the use of color images in a variety of applications including medical imaging, content-based image retrieval, biometrics, watermarking, digital inpainting, remote sensing, visual quality inspection, among many others. As a result, automated processing and analysis of color images has become an active area of research, to which the large number of publications of the past two decades bears witness. The multivariate nature of color image data presents new challenges for researchers and practitioners as the numerous methods developed for single channel images are often not directly applicable to multichannel ones. The goal of this volume is to summarize the state-of-the-art in the early stages of the color image processing pipeline."
