Book Description
Evidence suggests that medical innovation is becoming increasingly dependent on interdisciplinary research and on the crossing of institutional boundaries. This volume focuses on the conditions governing the supply of new medical technologies and suggest that the boundaries between disciplines, institutions, and the private and public sectors have been redrawn and reshaped. Individual essays explore the nature, organization, and management of interdisciplinary R&D in medicine; the introduction into clinical practice of the laser, endoscopic innovations, cochlear implantation, cardiovascular imaging technologies, and synthetic insulin; the division of innovating labor in biotechnology; the government- industry-university interface; perspectives on industrial R&D management; and the growing intertwining of the public and proprietary in medical technology.

Book Description
"BACKGROUND: The use of non-invasive cardiovascular imaging tests for diagnosing coronary artery disease (CAD) has risen dramatically over the last decade. However, guidelines for the diagnosis and management of patients with stable ischemic heart disease reported a lack of attention devoted to users' satisfaction, and repeatedly documented the importance of patient-oriented research to guide clinical decision-making. In this context, this study aims to contribute to the understanding of patient and physician preference in relation to the choice of cardiovascular imaging tests. METHODS: A discrete choice experiment (DCE) questionnaire on a convenience sample from the Royal Victoria cardiology clinic was used to systematically elicit patient and physician preference toward diagnostic imaging tests. Tests were differentiated using 6 attributes (patient out-of-pocket cost, risks and side effects, type of procedures, diagnostic accuracy, type of scanner and test duration). A choice-based conjoint analysis with hierarchical Bayes estimation was performed with Sawtooth Software. RESULTS: One hundred and forty-eight cardiac patients and 63 physicians completed the DCE. Risks and side effects had the highest impact on patients' preference (30%). Patients assigned notably high utility to tests with milder side effects (+97.7), while avoiding exposure to ionizing radiation (-36.7) and risks associated with exercise and the use of pharmacological agents inducing direct coronary arteriolar vasodilation (-61.0). Physicians attributed more importance to costs for patients (29%). CONCLUSIONS: Patients' preference was most determined by the risks and side effects associated with cardiovascular imaging tests, while physicians preferred less costly alternatives. When engaging in shared decision-making with patients, physicians should discuss the risks and side effects associated with cardiovascular imaging tests. In aiming for the best possible care, the clinical implementation of safer, more accurate and cost-effective imaging tests for diagnosing CAD may improve users' satisfaction and health outcomes." --

Book Description
Exploring the question as to why more than half the world continues to have little or no access to medical imaging and radiology, this important second edition, fully revised and expanded, offers not only answers but practical solutions, providing new tools, ideas, and strategies for bringing vital radiology to low-resource areas. Based on RAD-AID’s ten years of work (2008-2018) serving indigent communities around the world, the book’s interdisciplinary approach offers the synthesis of business management, government policy formulation, clinical methods, and engineering in order to integrate economic development, technology innovation, clinical model planning, educational strategies, and public health measures. The gold-standard title in the field, Radiology in Global Health, 2nd Edition is intended for a broad audience, including physicians (especially radiologists and radiology residents), radiology technologists, radiology nurses, sonographers, hardware/software engineers, policy-makers, business leaders, researchers, and public health specialists at all levels who use or implement health care services for underserved populations. In addition, as health care providers use radiology in the process of clinical decision-making, this title is also designed for clinical physicians, nurses, nurse-practitioners, physician assistants, and paramedical personnel. Administrators and public health personnel will also be interested, as the planning of radiology services for health care systems at both the facility level and at the population level requires a clear understanding of the technological challenges and management opportunities.

Book Description
Performing any diagnostic test in medicine is always a matter of trying to get the condition of the patient diagnosed properly with the least effort, exposure, discomfort and at the same time with the lowest possible error probability. Pre-test probability is helpful but often imprecise, effectively overestimating the patient's risk profile. In a broader prevention objective, the phases of a disease, its onset, progression, and complications must be taken into account. The negative predictive value, which is so important, has in turn its main limitation in identifying the healthy patient, that is, the one who does not belong to any cluster of patients in which we would act in terms of prevention. In coronary syndromes, the goal is instead to evaluate coronary heart disease, from mild to more extensive and significant forms. For this purpose, it is necessary to use parameters that investigate different and complementary aspects: stenosis, ischemia, the morphology of the atherosclerotic plaque, metabolic processes, in particular vitality and apoptosis, the presence of inflammatory processes. The possibility, already present thanks to Hybrid Imaging, of 'joining’ exams that study different aspects, will allow the patient to be increasingly characterized not only from a diagnostic point of view but also from a prognostic and personalized therapeutic choice.

Book Description
This book focuses on congenital heart disease (CHD) and emerging imaging technologies. It covers all clinically relevant aspects of the fascinating new cardiac imaging technologies, including a comprehensive explanation of their basic principles, practical aspects of novel clinical applications, and detailed descriptions of specific uses in the broad spectrum of clinically important adult CHD. Innovations and emerging technologies for diagnosis and therapeutics, evaluation and treatment are continually evolving, and due to these advances in non-invasive diagnosis, there has been a significant improvement in the survival rates for CHD patient. Novel approaches to trans-catheter interventions and advances in echocardiography, MRI and CT imaging are being developed and incorporated into routine clinical practice, while emerging three-dimensional printing technologies are fundamentally affecting patient care, research, trainee education, and interactions between multidisciplinary teams, patients, and caregivers. In addition, translational technologies on the horizon promise to take this nascent field even further. Exploring the applicability of these emerging technologies in improving our understanding of complex congenital cardiac defect anatomy and physiology will provide new treatment options for this unique population. Written by experts in the field who are also involved in patient care, this book discusses the practical application of innovations in advanced multimodality imaging in the daily clinical routine and offers tips and tricks for beginners.

Book Description
In this book, a strategy for medical decision diagnosis in cardiac imaging with MRI was depicted. This approach stipulates to conceive a 5D model, which depends on five dimensions: anatomical structure of the heart in 3D, temporal dimensions as well as a functional dimension of blood flow for the detection of stenosis and valvular regurgitation. Furthermore, a comparative study of the practical tools, which exploit the fifth dimension of flow for the deduction of the medical inference in the clinical routine. This contribution was considered for a stenosis aorta, which consists to make a 3D model and to solve the Navier-stokes equations for the laminar and viscous blood fluid to deduce the proposed model 5D (3D+time+flow). The extraction of measurements (field of the vortex, masses of flow, static pressure, Reynolds number) based on the fifth dimension is used to classify the area and the degree of stenosis. With the increasing demand for high-resolution simulations, it has become important to study the cost and response time of digital solvers that could take benefit of recent architectures including multi-core processors. In this work, the simulation, an efficient solver for the resolution based on the heterogeneous (CPU/GPU) architectures of Navier-Stokes (NS) equations relating to flows of incompressible fluids was assessed.
