There is a paid version of Horos called ‘OsiriX MD’, which is produced by Pixmeo, however it is expensive so not ideal for basic teaching purposes, although has great functionality. This programme is only available on Apple computers, hence why so many radiologists own MacBooks. This is a free open source version of the software used by the Royal College of Radiologists for the viva part of the Final FRCR 2B exam, so obviously it makes sense to use it for teaching as well.

A popular software for radiologists working in the UK is currently a programme called ‘ Horos‘.
