METHOD AND SYSTEM FOR DETERMINING THE BPE IN A CONTRAST MEDIUM-ENHANCED X-RAY EXAMINATION OF A BREAST

One or more example embodiments of the present invention relates to a method for determining a Background Parenchymal Enhancement (BPE) in a contrast medium-enhanced X-ray examination of a breast comprising providing images of the X-ray examination, the images having been taken after administration of the contrast medium, the images comprising at least one low energy (LE) image taken at a predetermined low X-ray energy and a high energy (HE) image taken at a predetermined high X-ray energy, creating an iodine image from the LE image and the HE image and calculating a volumetric BPE as a sum of all pixel values in the iodine image for which the following two conditions apply i) iodine enrichment is present in the iodine image, and ii) fibroglandular tissue (FGT) is present. The method further includes obtaining BPE result data based on the iodine image and volumetric BPE and outputting the BPE result data.
