Medical Imaging describes the discovery and development of diagnostic imaging technologies, explaining how the technologies work and exploring some of the issues that such powerful and expensive technologies create. The book begins with the discovery of X-rays in 1895 and traces the history of imaging technology through today?s tools, such as X-ray computed tomography, magnetic resonance imaging (MRI), functional imaging by positron emission tomography (PET), and single photon emission computed tomography (SPECT).
The contribution of these expensive technologies to the rising cost of healthcare in the United States and the unequal distribution of imaging diagnostic facilities, particularly in developing countries, is also considered. In addition, the book explores potential ethical issues that have surfaced concerning reportability of incidental findings during a scan, applications of imaging tools in lie detection, and admissibility of medical images as evidence in courts of law.
