Bone Arches: Performance of Pseudo-scanner Sequences in Segmenting the Extent of the Tumour and in Planning Surgical Resection Using the CT Scan as a Reference

The goal of this exploratory interventional study aims to evaluate the performance of "pseudo-scanner" MRI sequences in delineating the tumor extent within bone sarcomas and its ability to serve as a reference for designing cutting guides and enabling "navigation" during the surgical procedure, thus exploring the possibility of replacing the scanner to minimize exposure to ionizing radiation in patients with sarcoma.
