Undoubtedly, both Damadian and Lauterbur made major contributions to MRI imaging and scanning. Without Damadian’s relaxation discoveries that showed sharp discrimination between tissues and particularly a serious disease like cancer, there would have been no reason to entertain or even consider a method for displaying the relaxation differences so that they could be visualized as an image. Furthermore, except for the relaxation differences discovered by Damadian, there would be no reason to expect that such an image would show anything, i.e., that any tissue NMR contrast existed with which to make an image.
