Segmentation of MR-guided, high intensity, focused ultrasound treated lesions based on diffusion-weighted imaging and interactive information

Abstract

As the gold standard of traditional ablation treatment area, DCE-MRI has the disadvantages of slow imaging speed and only single examination during surgery. DWI is gradually being adopted as a new alternative. Considering the complex lesion status of uterine fibroids DWI, the interaction-based image segmentation method has a wider range of applications. Our proposed segmentation algorithm can be applied to a variety of cases and achieves a good segmentation Dice of 0.85.
