Facebook AI produces accurate MRI images 4 times faster than current tech:
Two years ago a team of radiologists from the New York University Grossman School of Medicine joined forces with Facebook's Artificial Intelligence Research (FAIR) group to try and develop a neural network that can produce effective MRI scans from as little data as possible.
[...] The collaborative project, called fastMRI, produced an AI model that can generate detailed MRI images from a quarter of the data traditionally needed. However, as outlined in a blog post penned by the Facebook AI team, creating accurate MRI images was only the first step for the researchers.
"Generating an accurate image isn't the only challenge," the Facebook team writes. "The AI model must also create images that are visually indistinguishable from traditional MRI images. Radiologists spend many hours carefully analyzing these images and an unfamiliar look and feel could make radiologists less likely to adopt fastMRI in their practices."
[...] "This study is an important step toward clinical acceptance and utilization of AI-accelerated MRI scans because it demonstrates for the first time that AI-generated images are essentially indistinguishable in appearance from standard clinical MRI exams and are interchangeable in regards to diagnostic accuracy," says lead author on the new study, Michael Recht. "This marks an exciting paradigm shift in how we are able to improve the patient experience and create images."
The results produced by the fastMRI project are open source, so the research team is hoping MRI hardware vendors can begin rapidly incorporating the new algorithms into their products. The innovation should also be easily incorporated over the next few years into pre-existing MRI hardware currently in hospitals, making patient experiences more comfortable while expanding MRI access to a greater number of people.

This is a potential disaster for MRI manufacturers, cutting their market by up to a factor of four in the long term and potentially freezing sales in the short term. Hospitals may be unable to recoup their investment in the expensive hardware they already have as prices drop. You can expect the medical industry to fight adoption of this technology for as long as possible.

MRI machines could have coin slots into which patients pay with plastic coins as they enter the machine. In order to fund the cost of the expensive machine.
Nevermind doctors, nurses and other professionals.

Probably not. I don't see Facebook manufacturing the machines. What I see is Facebook licensing this stuff, so they can collect rent on a field that isn't remotely related to social networking.

That will be part of the licensing agreement, of course.
Speaking of which - Facebook seems to suddenly have "connected" with me. In the past, I've not seen advertisements, at all. Recently, some ads have gotten through. In the past several days, those ads have become "relevant". Guess I need to go in, and double check all the permissions that "users" are permitted to change. Something is new and different . . .

Something does not make sense here?
Yes, I get it that you could get four times as many MRIs done on the same equipment.
But why would prices drop? If anything, I can see this new technology as a way to raise prices.
Demand for MRIs can rise, because now there are four times as much capacity available. MRIs can be ordered for lesser and lesser reasons. Patients don't need to know whether the MRI was actually necessary.

Same results with less data means the MRI machines can be made with less accuracy and/or fewer sensors while still producing acceptable results. Machines become cheaper.
Alternately, the improved analytical capability of the software should be able to provide more detail with the same raw data, improving the diagnostic capabilities of existing machines.

Imagine if the doctor could just answer a few questions about the patient, and an AI could generate "MRI scan" images for the doctor.
Just as an AI can generate completely fake human faces. [thispersondoesnotexist.com]

I wonder if this new image magic (or similar) will also work with CAT (X-ray) scans? Reducing the amount of X-ray images required to build up a 3D image seems like it would have health benefits (lower radiation exposure) in addition to the cost benefits.

The MRI still has to studied. This probably will take about the same amount of time as it currently does. This opens up the need for more doctors, or possibly outsourcing the work to other countries, which has the effect for further increasing income to the hospital. They will make more money with this, if it actually works properly.

How about for patients?
Sounds like it is including less source detail and more artifacts from AI.
I'm no radiologist, but that sounds kind of undesirable to me.

Exactly. This "AI" image enhancing product that inserted some celebrities face into the picture where only a window existed in the original was what sprang to mind for me.
