An MR when someone has a problem is pretty helpful.

Screening MR is not really a good thing except in a very narrow range of conditions - you just generate unnecessary procedures, more imaging and stress.

In regard to low field MR, the likes of Siemens Deep Resolve and their low field magnet (0.55T) have taken this a long way, and really improves image quality. It looks useful for imaging around implants and metal.

If you have a major issue, say a tumor, MRI is great, but for smaller things I agree with you that a single image is not great for a quantitative assessment. What does have a lot of value is when you have a baseline image and you perform yearly scans that are compared against each other (similar to how carotid ultrasounds are used for cholesterol assessment)

The articles I link to say the opposite. MRI as a screening tool has limited application - it causes more problems than it solved.
