MRI radiomics to predict recurrence and prognosis in patients with soft-tissue sarcoma

18F-FDG PET/CT imaging is an essential imaging modality for cancer diagnosis. Previous studies suggested that the maximum standard uptake of 18F-FDG PET is negatively correlated with the prognosis in sarcoma patients. However, PET/CT imaging involved systemic radiation exposure. It is recommended to limit the frequency of scanning, in particular for young patients or treatment monitoring. MRI is a supplementary imaging tool. The aim of the study is to assess the role of MRI radiomics for recurrence and prognosis prediction in soft-tissue sacroma.
