A system and method for presenting experimentally-determined data relating to a region of interest on a medical patient to a user. A computer memory stores a ROC analysis of historical data for a region of interest of a plurality of different subjects. A computer processor is programmed to compare the experimentally-determined data to historical data based on the ROC analysis of the historical data and identify the experimentally-determined data to be utilized in reaching an at least preliminary conclusion regarding the medical patient. A display device is operatively connected to the computer processor to present a visible display graphically depicting a result of the comparison performed by the processor.
