@pc2018 There are many disorders and diseases being diagnosed now from images of heart and lungs, etc. Most of them are wrong. We need to move toward genetics and chemistry and other solid sciences to sort it out. At one point, 3 pros "interpreted" my images of "ground glass", and they each provided a different scenario. ALL, Arthritis, I have forgotten the other. One of my Cardiologists says that genetics is good only for locating relatives and ancestors. I think he must have located the chimpanzee in his own tree. oldkarl
