While this work is great, this will not directly lead to "sharper MRI scans". This is about better modelling of NMR signals, which may eventually lead to better MRI, but it is still pretty far away from imaging. If you want how we use simpler signal models in physics-based reconstruction to improve MR images, you can look at our paper: https://doi.org/10.1098/rsta.2020.0196

FYI if you're getting a contrast MRI in the near future, avoid vitamin c. https://hscnews.unm.edu/news/unm-scientists-discover-how-nan...

Getting one on Monday, have a slight cold and took liposomal vitamin c just hours ago!

Thanks for making me aware!

not only vitamin c but fruits containing oxalic acid if I read that right. But I'm far more interested in when such contrast agents are warranted, because I'm not aware that in Europe that contrast agent would be used that much for MRI

thanks

I thought I read that in general it’s just better to decline contrast because it doesn’t actually add value to the scan.

After reading the article I get what it’s saying.. but isn’t any MRI _technically_ physics-based.

Does seem like advertising “rack and pinion” steering on a car…

Here's the paper.[1] No paywall this way; U.S. Government funded research. The paper claims an associated Github repository but there is no obvious link. There's no imagery in the paper, just the development of the math. So this may or may not help much.

I think the source code is here? https://github.com/pinheirothiagoj/NMR_Molecular_Eigenmodes_...

Seems right to me, same link as in the PDF's Data Availability section.
