Since 2015 (currently 2021), there are just 47 MRI questions in medical sciences. I have personally witnessed how MRI questions disappear within about two weeks, leaving a 404 error. I suspect people are afraid to ask and answer medical questions due to current forum policies, and are further reluctant to ask questions that will likely be deleted.
Compared to the ~40 million scans per year in the US alone, 47 questions in 6 years is maybe telling us something. I sometimes feel like we're in the dark ages of MRI-informed medicine and many doctors are effectively practicing medicine blind. Apparently, doctors are not allowed to post questions with an attached MRI image unless they first publish a paper and link to it (according to current take-down rules).
What is blocking questions on https://medicalsciences.stackexchange.com/questions/tagged/mri and how do we start to change this?
