RefScan is hardly the only MRI-geek website out there; another great one is Revise MRI, by Dave Higgins Ph.D. It’s primarily an educational resource, but there’s also a blog (Revising MRI) which has a broader scope. There’s even a discussion forum where people can ask MRI physics questions.
Some examples of cool posts on the blog are a short discussion of statistical methods for testing agreement, ruminations on teaching the gradient echo first, and a series of posts called “Use MRI for: …” (like bees, or lying, or mystical experiences…). Plus notable quotes by Erwin Hahn and Edward Purcell.
