The goal of this observational study is to evaluate the feasibility and clinical utility of radiomics to diagnose peri-lesion tumour infiltration of tumours in participants with a suspect of Bone Cancer Tumor or Soft Tissue Sarcoma (STS). The main questions it aims to answer are: * is radiomics able to identify the ratio of participants truly diagnosed as positive to all those who had positive test results? * is radiomics able to identify the likelihood that a participant who has a negative test result indeed does not have the disease? Participants eligible for this study will get a MRI as part of their regular medical care. The only difference is that their data will be recorded and anonymously analyzed.
