In my ? rst days as a Radiology resident I remember myself in dire need of a book in which I could begin to study the specialty. In those days I was thirsty for radiolo- cal knowledge and was recommended a classic manual on conventional chest X-ray which was the very same the oldest radiologist of the staff had studied when he was a beginner. Unfortunately the book I was recommended covered less than 5% of the specialty as it is conceived nowadays. "Learning Diagnostic Imaging. A Teaching File" is intended to provide medical students, residents of Radiology, and anybody else beginning to be involved in the radiological world, with a useful tool that gives them a quick and comprehensive overview of Radiology. With this book, written in a user-friendly format, Radiology residents, nurses, technicians, and medical students would see their ? rst radiolo- cal images in a sort of introduction of what will become their professional activities in the rest of their lives.

This book is an introduction to diagnostic radiology (including nuclear medicine). Written in a user-friendly format, it takes into account that radiology is divided into many subspecialties that constitute a universe of their own. The book is subdivided into ten sections, such as musculoskeletal, thoracic, gastrointestinal, cardiovascular and breast imaging. Each chapter is presented with an introduction of the subspecialty and ten case studies with illustrations and comments.
