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, 2^nd 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.
