Question 26 from the second paper of 2012 and the identical Question 6 from the second paper of 2006 ask the trainee to discuss the role of interventional radiology. They may be at least as vague as the questions that asked about the role of ultrasound in critical care. The questions favoured a trainee who can come up with a structure for this question quickly, and spout a bunch of indications. The answer offered below divides the issue into therapeutic and diagnostic roles, and then discusses the limitations of interventional radiology as a whole. This sort of structure lends itself well to a tabulated format, which should be memorable and easily reproduced should such a question ever appear again.
