Filly's 6th Law
Never turn off the main computer bank.
In this “law” the main computer bank is your brain! There are many fallacies about “numbers” in medicine. The point here is that you are an educated radiologist often with years of diagnostic experience. Then along comes a pundit or researcher who says, “use my number” (Oh, and forget everything else you have learned). This advice is almost invariably wrong. For example, your eye is telling you that something is not right, but “it measures within normal limits” by some supposed Guru’s paper. If your experienced eye says, “worry,” but “the number” says don’t worry… WORRY!
