Abstract
Accurately visualizing and editing tumor progression in medical imaging is
crucial for diagnosis, treatment planning, and clinical communication. To
address the challenges of subjectivity and limited precision in existing
methods, we propose SkEditTumor, a sketch-based diffusion model for
controllable tumor progression editing. By leveraging sketches as structural
priors, our method enables precise modifications of tumor regions while
maintaining structural integrity and visual realism. We evaluate SkEditTumor on
four public datasets - BraTS, LiTS, KiTS, and MSD-Pancreas - covering diverse
organs and imaging modalities. Experimental results demonstrate that our method
outperforms state-of-the-art baselines, achieving superior image fidelity and
segmentation accuracy. Our contributions include a novel integration of
sketches with diffusion models for medical image editing, fine-grained control
over tumor progression visualization, and extensive validation across multiple
datasets, setting a new benchmark in the field.
