Trauma radiology comes up fairly frequently in the exam. For instance, recently Question 12.1 from the second paper of 2014 showed the candidates a CT with a racture through the sella turcica, and Question 20 from the second paper of 2013 showed them a ruptured liver with lots of intraperitoneal blood. It is probably impossible to formally prepare for such image-based questions, given the randomness and improbability of what may be thrown before you. All one can do is know what has already happened. Ergo, this chapter presents the discussion points from previous trauma radiology questions.
A good recent article discusses these points as well as offering tables of injury severity grading.
