Book excerpt: This book takes account of recent changes in the Fellowship of the Royal College of Radiologists (FRCR) Part 2A examination. It includes basic radiological science questions as well as the original clinical imaging component, and in particular it discusses cross sectional imaging at an advanced level. Many of these questions are also very useful in preparation for the American Boards Exam in Radiology. Unlike other books in this field, this essential guide provides full explanatory answers and bibliography. Questions are divided into subject chapters corresponding to those in the current FRCR Part 2A syllabus, and structured in an identical fashion to the actual exam.
