Multi-scene model shows success for precise preoperative and intraoperative segmentation of acute VCFs
This study aimed to develop a multi-scene model, Positioning and Focus Network (PFNet), for automatically segmenting acute vertebral compression fractures (VCFs) from spine radiographs. Conducted across five hospitals from 2016 to 2019, the study included both acute VCF patients and healthy controls. PFNet was trained with radiographs from Hospitals A and B, and tested on datasets from Hospitals A-E. The
