Useful in many areas of medicine and biology, Bayesian methods are particularly attractive tools for the design of clinical trials and diagnostic tests, which are based on established information, usually from related previous studies. Advanced Bayesian Methods for Medical Test Accuracy begins with a review of the usual measures such as specificity, sensitivity, positive and negative predictive value, and the area under the ROC curve. Then the scope expands to cover the more advanced topics of verification bias, diagnostic tests with imperfect gold standards, and those for which no gold standard is available.

Promoting accuracy and efficiency of clinical trials, tests, and the diagnostic process, this book:

• Enables the user to efficiently apply prior information via a WinBUGS package
• Presents many ideas for the first time and goes far beyond the two standard references
• Integrates reader agreement with different modalities X-ray, CT Scanners, and more to study their effect on medical test accuracy
• Provides practical chapter-end problems

Useful for graduate students and consulting statisticians working in the various areas of diagnostic medicine and study design, this practical resource introduces the fundamentals of programming and executing BUGS, giving readers the tools and experience to successfully analyze studies for medical test accuracy.

All those concerned with biological anthropology, both clinicians and researchers, will find this book of great interest.

This book has been specifically designed to serve as a quick reference that will be of immediate help in decision making. The book is ordered alphabetically according to diagnoses. The intention is that the clinican consults the information on a suspected diagnosis, and then considers the surgical and radiological differential diagnoses that are listed. A total of 80 common diagnoses are covered. For each diagnosis, the left-hand page presents information relevant to the surgeon, while the right-hand page is designed for the radiologist. The information for the surgeon comprises clinical insights, including symptoms, warnings, controversies, important facts of which the surgeon should be aware, and the surgical differential diagnosis. The intention is to enable the surgeon to request the most suitable investigation using the appropriate terminology, ensuring that the correct test is done within the correct time frame. The radiologist is provided with lists of the primary and follow-on investigations, the imaging findings, and helpful tips, as well as the radiological differential diagnosis. Informative supporting images are included for each diagnosis. The authors are all experts in their fields, with extensive practical experience and in-depth knowledge of new imaging techniques. This book belongs in the pocket of every student, house officer, resident, medical officer, or generalist consultant who may be the first practitioner to see the patient.

To improve efficiency and reduce administrative costs, healthcare providers, insurance companies, and governments are increasingly using integrated electronic health record (EHR) and picture archiving and communication systems (PACS) to manage patients' medical information. Reflecting the latest applications of PACS technology, PACS and Digital Medicine: Essential Principles and Modern Practice discusses the essential principles of PACS, EHR, and related technological advancements as well as practical issues concerning the implementation, operation, and maintenance of PACS and EHR systems. The book focuses on various components of PACS that use state-of-the-art technologies. The authors first present topics to consider prior to implementation, including design principles for PACS components and theory. They also cover post-installation quality control; security and privacy policies; maintenance, including upgrade/integration with other information systems; and governing standards. Each chapter includes an introduction to basic concepts and principles relevant to the topics, before exploring challenges that PACS users may encounter in daily work. Discussions are supplemented with more than 130 illustrations, along with case studies of implementation in two organizations. A useful guide and broad overview of the field, this book presents key principles and practical steps for PACS and EHR implementations and maintenance. Although the technology and standards of healthcare IT will evolve over time, the theory and practical advice found in this text will remain pertinent in the future.

The aim of this book is to present statistical problems and methods in a friendly way to radiologists, emphasizing statistical issues and methods most frequently used in radiological studies (e.g., nonparametric tests, analysis of intra- and interobserver reproducibility, comparison of sensitivity and specificity among different imaging modality, difference between clinical and screening application of diagnostic tests, ect.). The tests will be presented starting from a radiological "problem" and all examples of statistical methods applications will be "radiological."

Clinical applications for each major vascular territory are covered in-depth, with clear descriptions of the examination technique for assessing the peripheral vasculature including the aorta to detect various vascular pathologies. The section on MR angiography provides a comprehensive overview of the current state of magnetic resonance (MR) vascular imaging. The basic principles and technical features of MR angiography are outlined, with chapters on fundamentals of MR angiography and commonly used pulse sequences and contrast dosing. Specific chapters focus on each particular vascular territory including the extracranial and intracranial circulation, the pulmonary circulation, the thoracic and the abdominal aorta, the renal, and mesenteric circulation and both the lower and the upper extremity circulation. Easy to follow clinical protocols for angiographic imaging for the different vascular regions are provided. The text also addresses imaging of the venous circulation using MR and CT angiography.

Data mining can help pinpoint hidden information in medical data and accurately differentiate pathological from normal data. It can help to extract hidden features from patient groups and disease states and can aid in automated decision making. Data Mining in Biomedical Imaging, Signaling, and Systems provides an in-depth examination of the biomedical and clinical applications of data mining. It supplies examples of frequently encountered heterogeneous data modalities and details the applicability of data mining approaches used to address the computational challenges in analyzing complex data. The book details feature extraction techniques and covers several critical feature descriptors. As machine learning is employed in many diagnostic applications, it covers the fundamentals, evaluation measures, and challenges of supervised and unsupervised learning methods. Both feature extraction and supervised learning are discussed as they apply to seizure-related patterns in epilepsy patients. Other specific disorders are also examined with regard to the value of data mining for refining clinical diagnoses, including depression and recurring migraines. The diagnosis and grading of the world's fourth most serious health threat, depression, and analysis of acoustic properties that can distinguish depressed speech from normal are also described. Although a migraine is a complex neurological disorder, the text demonstrates how metabonomics can be effectively applied to clinical practice. The authors review alignment-based clustering approaches, techniques for automatic analysis of biofilm images, and applications of medical text mining, including text classification applied to medical reports. The identification and classification of two life-threatening heart abnormalities, arrhythmia and ischemia, are addressed, and a unique segmentation method for mining a 3-D imaging biomarker, exemplified by evaluation of osteoarthritis, is also present

Intravoxel incoherent motion (IVIM) refers to translational movements which within a given voxel and during the measurement time present a distribution of speeds in orientation and/or amplitude. The concept was introduced in 1986 together with the foundation of diffusion MRI because it had been realized that flow of blood in capillaries (perfusion) would mimic a diffusion process and impact diffusion MRI measurements. IVIM-based perfusion MRI, which does not require injection of any tracer or contrast agent, has been first investigated in the brain, but is now experiencing a remarkable revival for applications throughout the body, especially for oncologic applications, from diagnosis to treatment monitoring. This book addresses a number of highly topical aspects of the field from leading authorities, introducing the concepts behind IVIM MRI, outlining related methodological issues, and summarizing its current usage and potential for clinical applications. It also presents future research directions, both in terms of methodological development and clinical application fields, extending to new, non-perfusion applications of IVIM MRI, such as virtual MR elastography.

This book addresses the question 'What is physics for?' Physics has provided many answers for mankind by extending his ability to see. Modern technology has enabled the power of physics to see into objects to be used in archaeology, medicine including therapy, geophysics, forensics and other spheres important to the good of society. The book looks at the fundamental physics of the various methods and how they are used by technology. These methods are magnetic resonance, ionising radiation and sound. By taking a broad view over the whole field it encourages comparisons, but also addresses questions of risk and benefit to society from a fundamental viewpoint. This textbook has developed from a course given to third year students at Oxford and is written so that it can be used coherently as a basis for shortened courses by omitting a number of chapters.

Since their discovery by Becquerel and RAntgen, ionising radiation and detectors for ionising radiation have played an ever more important role in medical diagnostics and therapy. The use of scintillating materials in the detection of ionising radiation for medical imaging is the main topic of this book intended for an audience of physicists and engineers. The book will be useful both to new researchers entering the field and to experts interested to learn about the latest developments.

It starts with an overview of the state of the art in using radiation detectors for medical imaging, followed by an in depth discussion of all aspects of the use of scintillating materials for this application. Possibilities to improve the performance of existing scintillating materials and completely new ideas on how to use scintillating materials are discussed in detail. The first 4 chapters contain a general overview of the applications of radiation detectors in medicine and present a closer look at the 3 most important subfields, X-ray imaging, gamma ray imaging and PET. One chapter is devoted to semiconductor detectors, a promising new area, and two chapters are devoted to recent technical advances in PET. The remaining 5 chapters deal with scintillating materials and their use in medical imaging.
