To determine the frequency and classification of addenda seen in paediatric brain magnetic resonance imaging (MRI) reports. A retrospective review of the addenda of brain MRI reports from a large tertiary children's hospital was undertaken between January 2013 to December 2021 and a subset of above radiology reports was used to classify addenda over 6-month periods, October to March, spanning 2018 to 2021. A radiology fellow and a medical doctor classified the addenda into previously published categories using their best judgement. Out of 73,643 brain MRI reports over 9 years (108 months) included in the study, only 923 reports (1.25%) had addenda. There was a total of 13,615 brain MRI reports from 6-month periods, of which only 179 reports (1.31%) had an addendum. The number of errors according to categories were: observational 88/13,615 (0.65%); interpretational 16/13,615 (0.12%); non-observational and non-interpretative 82/13,615 (0.6%). Notifications to referring physician made in 29/13,615 (0.21%). The overall proportion of addenda to the brain MRI reports of children in the present study was low, at 1.25%. Categorisation of different addenda revealed the most common errors to be observational in 0.65%, including under-reading in the region of interest in 0.25%. Appropriate measures can now be introduced to minimise the error-based addenda further and improve MRI diagnosis in children. Other paediatric practices may choose to follow suit in evaluating their addenda and errors to improve practice. •Overall, the proportion paediatric brain MRI report addenda was low: 1.25%.•The most common errors were observational (0.65%) including under-reading (0.25%).•Other paediatric practices should evaluate their addenda to improve practice.
