Feasibility and repeatability of PET with the hypoxia tracer [18F]HX4 in oesophageal and pancreatic cancer

PET scanning with [18F]HX4 was feasible in both EC and PC patients. Amount and location of elevated [18F]HX4 uptake showed good repeatability, suggesting [18F]HX4 PET could be a promising tool for radiation therapy planning and treatment response monitoring in EC and PC patients.
