CT is not much faster than a quick T1 and T2 from a portable MRI these days. By the time you transport to the CT suite, set them up, run the scout, etc., you could have acquired the MR bedside.

Edit: To add some clarity, portable MR systems are low field, so that means the scans will be lower SNR and resolution, which are much faster to acquire. I think it would also rule out diffusion scans, since those require high gradients. MR acquisitions are also much faster nowadays due to compressed sensing and deep learning reconstructions.




There's no portable bedside MR available though.

Even if you have an MR machine with a very low strength primary fields you'll still need to consider safety issues related to the gradients and coils.


Portable low field bedside MRI has been on the market in the US for a few years. See Hyperfine Swoop.
