The only other obstacle to the wider use of PET-CT is the difficulty and cost of producing and transporting the radiopharmaceuticals used for PET imaging, which are usually extremely short-lived (for instance, the half life of radioactive Fluorine-18 (18F) used to trace glucose metabolism (using fluorodeoxyglucose, FDG) is two hours only.
