All MRI brain studies involving cerebrospinal fluid shunts from September 2017 – April 2018 were filtered from the Royal Brisbane and Women’s Hospital imaging database. Clinician request forms and patient-completed safety questionnaires were retrospectively analysed for patient demographics, shunt type, pre- and post-MRI shunt settings, and accuracy of documentation.

A clinical standard was set: 95% of MRI request forms for cerebrospinal fluid shunt patients should state shunt type and setting; less than 80% of shunt settings should require correction by radiography staff after MRI.
