Workflow of ROI extraction and preprocessing and our DLR model. The ROI image is extracted from the raw CEUS video, if available; otherwise it is extracted directly from the existing CEUS images. The resized and grayscale ROI images are fed into our model which outputs the AI score and heatmap for each lesion. The radiologists provide an initial decision on each lesion and then adjust their decisions, if uncertain, based on the additional information provided by the DLR model. CEUS, contrast-enhanced ultrasound; PDAC, pancreatic ductal adenocarcinoma; CP, chronic pancreatitis; ROI, region of interest; AI, artificial intelligence; DLR, deep learning radiomics
