Researchers have developed a novel interactive lesion segmentation method for PET/CT scans, utilizing a scribble-conditioned ResEnc U-Net. This approach leverages user-provided scribbles to mark foreground and background, significantly improving segmentation accuracy. The model, initialized from weights of a previous challenge winner, was fine-tuned and ensembled to achieve a mean Dice score of 0.751 and a lesion-level F1 score of 0.733 after interactive correction.
