Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Is PET-CT scan better than PET or CT alone in diagnosing primary tumours in patients with unknown primary tumors? Can information obtained with PET-CT replace other clinical and radiological investigations? Is PET/CT cost-effective?
