> We already have a lot of MRI data.

That's true but not in a useful way for improving MRI screening.

What we have is lots of days from people who were sent to get an MRI because they had a complaint.

That's a very different group than people doing screening.

And the fact that they have a complaint (or have known risks) makes it easier to classify, compare and understand the data.
