This study investigates the case of repeated MRIs using data from Hacettepe University Hospitals. Results indicate that almost 34% of MRI consultations have to be repeated within the same year due to suboptimal quality that hinders correct assessment and diagnosis. Suboptimal quality refers to; movement artefacts, use of wrong scan technique or sequence, inexperienced reader and/or shortened time intervals. In fact, almost 30% of those repetitions result in a change in diagnosis. Results suggest that the probability of repetition is higher among women and children.
