This book addresses in a structured and multidisciplinary way the medical issues related to aging, paying particular attention to the role of diagnostic imaging in the field of cardiovascular, musculoskeletal, respiratory, neurological, urogenital and gastrointestinal diseases. The progressive increase of the average age of the population, of life expectancy and the improvement of the quality of life are common phenomena in many countries of the World. Over the years, the management of older persons seems to have had an increasing impact both on the socio-economic and on the medical-health level. Medicine, in all its branches, has in fact focused more and more on the health conditions of the elderly patient and its protection and, in this context, due to the increasing progress in the field of technology and imaging methods, the radiologist occupies a front-line position.
