In September 2009, the format of the written Radiology FRCR Part 2A examinations changed. The previous negatively-marked true-false MCQs have become obsolete, replaced by single best answer' (SBA)questions, with candidates selecting 1 of 5 options, without negative marking. The author team have themselves recently successfully sat the FRCR exam, and have prior experience in the SBA format, making them ideally suited to write such a book, and have produced an excellent revision guide for the new format exam. There are 750 stem questions covering all 6 modules, including a separate section with a 75 questions-per-module mock' examination which readers can use to test themselves against the clock, under examination conditions, to hone their technique. The questions have been extensively researched and cross-checked, with relevant topics being drawn from major radiology textbooks, as well as current radiological journals such as "Clinical Radiology" and "Radiographics". Answers are given with detailed explanations and references are provided, which can also be used for further reading as appropriate. As a bonus the authors pass on their own proven exam tips and techniques. Key Points - The authors recently sat exams themselves. It features over 700 questions.
