One of my docs told me that with head/neck cancer they are moving away from PET due to false positives. I haven't seen one but I understand that there is a new CT machine that doubles the amount of slices taken to produce the 3 dimensional image and that tumors the size of a grain of sand can be detected by the skilled eye of the radiologist. It is awesome the strides that are made daily in all kinds of cancer research. I firmly believe that there will some day be a cure for all cancer.
