> The average cost of a WB-MRI scan for NSCLC patients was £317 Wow! $3000+ here in the US. Ever get the feeling you've been cheated?

State of the art MRI machine costs $3 million up front. Would take 20 scans a week, every week, for 10 years to break even on that investment at $300 per scan. Not counting physician & staff time or cost of capital.

Yes but you don't do 20 scans a week, you do that per day

With sufficient software and computational horsepower, a single whole-body MRI could replace most diagnostic imaging systems, I'd wager. Computer models regularly outperform radiologists in diagnosing several conditions involving structural abnormalities.

CT scans still have higher resolution than MRI for certain vascular and cardiac imaging studies. The down side is radiation exposure.

they could still probably do a whole hell of a lot better with automated diagnosis.

Many doctors hate full body scans. Every individual has a handful of anomalies which are almost always benign. They show up on full body scans and chasing them down comes with cost and patient risk.

I have a hard time with reporting like this that doesn't quantify cost of biopsy on false-positives as well as cost of complications from examining false-positives.

Not all MRI machines are equal, though, so it's hard to tell without specifics.

A low field 0.2T machine might be $150k. A full bells+whistles 3T machine might be $3M.

> preferred by patients and involving less exposure to radiation

I thought MRIs didn't have any radiation exposure as opposed to X-Rays and CT scans; unsure about this benefit of less exposure to radiation from 1 whole-body MRI vs multiple MRIs (should be the same IMO)

Looks like you're pretty close: https://www.radiologybusiness.com/topics/business-intelligen...

>Ultimately, UVI increased appointment slots to 407 a week, efficiency was boosted to about 82%, and it is averaging 433 examinations per week.

That's for four machines.

My insurer pays like $450. The hospitals seem to be doing ok, if anything there are way too many MRIs out there.

A few years back that was the "japanese problem": the price of MRI machines started falling but the act itself (whose price is set by policy / negotiations) hadn't been revised yet, so every clinic started getting one, which contributed to the price falling, and a price revision or two later the price was revised to ~$100, but the cheap MRIs and habit to use them remained.

We're talking circa 2010, around the time of the obamacare debate in the US.

If you prepay, costs around $400 to $500, but that is not involving private insurance. https://www.mdsave.com/ Not affiliated, just interesting to see prices of various diagnostics around the US.

There are others that are less expensive if you do some searching, like https://radiologyassist.com/ (depending on where you live).

Also, if you call independent MRI centers they will usually give you a much lower cash price (but then insurance won't reimburse).

Another point to consider is that hospital MRIs can cost 10x (ten times) more than independent MRI centers.

And while we're talking about MRIs, it's important to mention that the safer contrast agents are the macrocyclics. Avoid the linear agents if you are concerned about possible gadolinium deposits in your brain and other organs, and potential kidney damage.

Out of all the things that the feds could be subsidizing. This one seems like a no brainer to me. Seriously we subsidized agriculture to avoid people starving. Why not MRI machines to avoid people dying from avoidable diseases? Instead of it being a luxury we could scan everyone once every 6 months.

Who am I kidding? That actually requires a forward thinking government.
