The power Doppler study adds about 30% more accuracy, since the abnormal blood vessels provide a road map to the tumor, however, detours on the road may occur with older 3-D systems in the presence of stones or calculi. Indeed, a US patent, number 5,860,929, was obtained by Norwegian scientists to determine power Doppler blood flows in optimally diagnosing PCa's. When a stone is identifiable, the sound waves bounce back so strongly that they create a false color pattern. This pattern to the trained clinician will not be mistaken for a tumor vessel.
