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 up to 20 patients with unresectable, non-metastatic, locally advanced un-resectable pancreatic adenocarcinoma (LAPAC).
After each FAZA PET-MRI scan, patients will be followed up via telephone, 48 hours after the imaging session to assure that the procedure was tolerated without side effects. Patients will undergo a FAZA PET-MRI scans before and after their standard of care radiation treatment.

The success of hypoxia-targeted therapies has so far been limited, a fact widely attributed to the absence of a reliable imaging biomarker for hypoxia that could easily be implemented into a routine clinical workflow. A compelling study has found the presence of hypoxia in pancreatic tumors using FAZA-PET imaging. The data derived from this alternative dual-imaging approach can be used to establish a patient-specific perfusion-to-hypoxia mapping, accounting for differences in tumour metabolisms. This technique was recently validated in a pre-clinical FAZA-PET/CE-MRI study of mice with orthotopically-implanted pancreatic patient-derived tumour xenografts.
The purpose of this study is to look for hypoxia in tumours using a PET scan in combination with MRI. The use of PET/MRI scans to measure hypoxia may be better and simpler than the approaches used previously. This study will assess whether or not PET/MRI scans can provide useful information about hypoxia in pancreatic cancer. Additionally, a recent study at the Princess Margaret Cancer Centre found varying levels of hypoxia in patients with pancreatic tumors, providing a rationale for incorporating hypoxia imaging and patient-specific treatment adaptation into the clinical management of pancreatic cancer.

- 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 radiation treatment.
- Tumor Hypoxia [ Time Frame: 2.5 years ]Hypoxic regions in the tumour are defined as regions for which the voxel-scale activity exceeds the mean activity in the left-ventricle blood pool by a ratio of 1.2. The fraction of such voxels in a given tumour defines the hypoxic fraction.
