Determination of quantitative vascularization parameters in SMI mode. Images show the workings of the image processing software, ImageJ. a In the SMI sonogram window, an area is selected (yellow polygon) to highlight nodes and parenchyma. The selected areas are listed in the ROI Manager window, and the grayscale mean values are determined. b For the selected node (yellow polygon) in the SMI sonogram image, a threshold is set, and areas are extracted that have grayscale pixel values above the threshold. The result is an image sequence that only contains areas with a positive flow signal. The measured value is the fraction of these areas within the total selected area of the node
