What should I look out for with AI in radiology & medical imaging?

Image analysis AI is a medical device: only use software with a CE marking under the MDR (class IIa or higher) for the exact purpose you deploy it for, and document how you validate and keep monitoring performance locally. You process special category personal data: ask where images are processed (on-premise, EU cloud or outside), whether they are pseudonymised and whether they are used for training, and sign a data processing agreement. Many vendors run on AWS or Azure or have been acquired by US groups, so check the current data location. The radiologist remains ultimately responsible for the report.
