Do you know which MRI you used? Not all are equal.
Most MRI are 1.5T powered, and you can’t get fine details until you hit 3T. And there are differences even in the 3T power range. There are higher powered MRI which are mostly only used in research, whilst it is a bit scary thinking about the sheer power of them but a 7T machine doing a full scan of you, would be guaranteed nearly to find anything wrong with you.
When I last looked the full body scans for sale seemed to used 1.5T setup, which seems like a waste. The 3T advanced scans looks much more detailed, but it just depends on where you live - I couldn’t find any around.

My knee and back was years ago, so probably the 1.5T. No idea on my dogs who have had the more recent MRIs. Their scans are incredibly detailed though, so maybe the 3T?
