This is a single arm, single centre, investigator initiated study to investigate the use of FAZA-PET in combination with MRI. FAZA is an investigational radiotracer used in PET scans. FAZA PET/MRI will be used to measure hypoxia in sarcoma tissues of 14 patients who plan to undergo neoadjuvant radiation/chemotherapy treatment.
After the FAZA PET/MRI scan, patients will be followed up via telephone, 48 hours after the scan, to see if there are any side effects due to FAZA. Patients may also be requested to repeat the FAZA scan after their standard of care radiation treatment.

Mutliple studies show that hypoxia in sarcoma has been consistently associated with poor treatment outcomes. Subsequently, there has been a study that shows inhibition of hypoxia-induced transcription factor (HIF-1 alpha), with radiation, was effective in disease treatment in pre-clinical models. This shows how important hypoxia was in playing a role in overall disease outcome and survival.
As a means of examining tumor features, such as hypoxia, hybrid PET/MR imaging combines the advantages of MRI's soft-tissue and contrast resolution with PET's functional metabolic capabilities. There have been few reports of using 18F-FDG in diagnostic PET/MRI. with the use of 18F-FAZA in this study, parameters such as diffusion, micro-perfusion, and contrast enhancement (as a surrogate marker for viable tumour tissue) can be simultaneously compared with the FAZA-derived pattern, in a single procedure.
The study is being conducted to measure the volume of hypoxic tumor in high-risk STS patients, using FAZA-PET/MRI, before and after neoadjuvant radiotherapy/chemotherapy.

- Drug: 18F-FAZA
18F-FAZA is a radiotracer used for PET imaging (in combination with MRI) to detect hypoxia in tumours. This scan will be done before and after their radiation treatment.
- Grade of FAZA uptake in the primary tumor [ Time Frame: 2 years ]Graded based on images from the 2-hour static scan: 0, uptake less than surrounding normal background tissues; 1, no regions of focal uptake higher than that of background; 2, focal uptake moderately higher than background; and 3, focal uptake markedly higher than background
