Huh? You don't have to come up with an interpretation. The brief says it "looks a lot like today's MRIs but at nearly a hundred times the speed". They don't explain why having a hundred times as many MRI images would lead to better diagnostic outcomes. It is not like ultrasound scanning is a new idea, and they don't give any particular reason why this suggestion was not used before (other than "...data?")

It's not just about better diagnostic outcomes. Currently MRIs are a horrible, claustrophobic experience, and MRI machines are so insanely expensive that it is a bigger deal just to prescribe one.

So even if it is only as good as an MRI, or even 80% as good as an MRI, if it is much cheaper and much more pleasant to go through, you will get MORE people doing it, and get it prescribed in more situations.

That's at least how I read the benefits, democratization of imaging techniques rather than just improvement.
