Ensuring privacy in MRI research is critical due to the sensitivity of medical data. In this education session, the risks of privacy breaches from MR data, and tips on how to minimise them, are explained with respect to the “Five Safes” of data privacy: Safe Output, Safe People, Safe Setting, Safe Data and Safe Output. The session touches on a wide range of security topics, from encryption of DICOM transfers and defacing of structural MRI scans, to disclosure risks in published outputs, to give an overview of the issues that need to be considered over the lifecycle of MR projects.
