I am told that before Lauterbur's 1973 Nature paper, there were reputable 
scientists who said you can't use radio waves to create useful images.  Of 
course MR imaging is really in the magnetic gradient, but it "uses radio 
waves to create images."  I can only imagine the resistance Lauterbur must 
have encountered in the early days.
