EMvision Research Notes, page-2827

I think you are right Vintage but the scans will also be usual for detecting other abnormalities as well.

This study is a data collection study of the EMVision emu™ brain scanner for patients not suffering from or suspected of suffering from an acute stroke for software algorithm development. This study collects EMVision brain scans and MRI scans from patients receiving a head MRI as part of their routine care. Scans are anonymised and enter the EMVision database for training and developing software algorithms. This study hypothesises that an expanded non-stroke dataset can improve the diagnostic performance of the emu™ brain scanner.
