"Using AI, it may be possible to capture less data and therefore scan faster, while preserving or even enhancing the rich information content of magnetic resonance images, says Facebook. The key will be to train artificial neural networks to recognise the underlying structure of the images in order to fill in detail omitted from an accelerated scan." Ah, right, what I want is for an ANN to invent information in a med…

Is that really the way to make the MRI faster? It seems like a time and motion problem. You lie in the machine for a long time but there's a lot of slack; the actual image process takes up barely any of the time. Remainder of time is spent waiting for things to whiz around and for the tech to click "next" on their console.
Adding more "cameras" to our MRI so we can do parallel imaging is expensive.

The FDA will probably set the low bar of validating that the reconstruction algorithm fares well in the face of a few abnormalities and call it a day, instead of the proper (admittedly infeasible) validation of testing against all abnormalities that the reconstruction algorithm will encounter. Facebook will probably happily jump over this low bar, and patients will get hurt.

Idk. A lot of the applications of AI to compressed sensing are resulting in plausible but inaccurate data being filled in. This is fine for, say, video games, but not as great for medical imaging I'd guess.

From the perspective of a MRI purchaser (say clinic or hospital director), maybe you can squeeze 1 or 2 more cases in a day, but it seems like a marginal improvement overall. I think cardiac is clearly the exception where you bring on board potentially new functionality with quicker acquisition.

I have talked at length with several people in the FastMRI project and in my opinion it is actually very dangerous. There is no feasible way to validate that such a model will not hallucinate normal tissue in the presence of a rare abnormality. The argument often used is that advanced reconstruction techniques such as compressed sensing have not required validating against very rare abnormalities, however when deep n…

What’s next, an AI to make a judicial verdict? Seriously though, this is very exciting. I can imagine a future in which medical diagnosis is damn near 100% accurate - all you need to do is lay down and get scanned and smelled by an all in one machine and your diagnosis is displayed with recommended treatment. If treatable with drugs or molecular repair, done on the spot.

We are in for some truly exciting times.
