Developing visual expertise:from shades of grey to diagnostic reasoning in radiology

One in fifty X-rays are misdiagnosed, which can jeopardise the health of the patient. While proper training and education is crucial to prevent this, very little is known about how radiologists are trained. This dissertation examines how experienced radiologists assess X-rays and how students can be taught to do the same. Eye tracking software was used to determine exactly which parts of the screen were being viewed. We found that systematically examining the entire X-ray was not as important as originally thought. It is much more effective to teach students what different diseases look like by having them compare X-rays, but this teaching method is currently being underutilised
