This Single Best Answer (SBA) textbook is designed specifically for postgraduate radiology students taking the Fellowship of the Royal College of Radiology (FRCR) Part 2 final exams. Part 2 comprises two elements: 2a includes a series of six multiple choice exams covering the major body systems; and 2b contains a written exam and an oral viva typically taken at the beginning of the fourth year of specialty training. These SBAs would also be useful for students in other fields.
