I enjoy this Doctors interview podcasts.
"In this episode, radiologist/engineer, Raj Attariwala, explains how he was able to apply his engineering background to create a unique MRI scanner that is capable of constructing whole-body images with a resolution that is unmatched in the industry."
The first part is about all kinds of imagining and the body
If you want to get to the meat of the MRI part, go to 1:04:03.
Otherwise, you can skip to 7:45 and bypass the intro, but if you haven't heard Peter Attia, it's a little introduction. .
