The question that needs to asked though is: what would you do with that information? Would you be willing to undergo biopsy (which is the standard for diagnosis) knowing there is a non-zero risk of complication. What if the biopsy is not conclusive? Do we then do a major surgery which includes risk of death? Imaging is NOT diagnostic for tumors. For most lesions, you have to take tissue samples.
