That’s a good idea, I learnt a lot by looking at my ‘series’ of MRI’s spanning over several years. Have you managed to look at your disks, did you see any changes ? Just in case you’re having trouble, or nervous of how to access your images, the viewing software is usually supplied on the disk and often starts automatically, after you insert the disk (though I’ve had one or two that don’t!). Let me know how you get on.
