The emphasis of this text is on cross-sectional CT and MR imaging. It highlights the current understanding and concepts in the state-of-the-art imaging of a wide range of diseases in the body. The multiple choice questions are organised according to body systems and imaging modalities. There are twelve sections in the book, testing the reader in a broad range of imaging knowledge. The questions are accompanied by expanded answers, which provide the reader with a summary of the key facts relating to particular topic. This intends to assist the reader in consolidating his or her understanding of the subject. The questions are devised in a format similar to those encountered in the Part 2a examination of the Royal College of Radiologist (UK) and the Part 2 examination of the Joint Australian and New Zealand College of Radiology. The work also intends to be relevant to candidates taking the American Radiology Board examinations.
