Fig. 4From: Exploring the prediction performance for breast cancer risk based on volumetric mammographic density at different thresholdsA visual comparison of “density map” using 0–15 mm threshold levels. Traditional volumetric density such as from the Volpara software uses a 0 mm threshold (no threshold). VPD0, volumetric percent density with a 0 mm threshold; VPD5, VPD with a 5 mm threshold; APD6, areal percent density with a 6 mm thresholdBack to article page
