This book focuses on how to perform and interpret X-rays examinations in countries where diagnostic imaging has not yet reached the stage of molecular imaging and where many primary care physicians have had little or no training in the interpretation of images both radiographic and sonographic. It provides images of common pathologies seen in many developing countries in a pattern format. These include chest musculoskeletal gastrointestinal and urinary tract patterns. The pattern recognition format has been used successfully both by national and international radiographic societies to educate.
