This book is to supplement major radiological textbooks for those preparing for the final examination for the Fellowship of the Royal College of Radiologists in the UK, the specialist Boards in the USA and other similar professional examinations. The first part of the book gives lists on differential diagnosis (concentrating on conditions of most relevance to radiological practice). These lists are supplemented with notes on useful facts and discriminating factors for the radiologist. The second part of the book gives notes on the radiological appearance of approximately 80 important diseases. This book does not include radiographs as the reader will have access to these in their main radiological textbook. The aim is to help in the logical interpretation of the radiograph.
