Diagnostic value of 18F-FDG PET/CT and MRI in patients suspected of cancer of unknown primary in the head and neck

There was no significant difference in the sensitivity between FDG-PET/CT and MRI in patients with head and neck cancer or CUP. Adding MRI to the diagnostic workup in occult cancer did not significantly improve detection of primary tumours. In case of malignant tumours, 50% were oropharyngeal cancer and required MRI for preoperative planning.

Abstract

There was no significant difference in the sensitivity between FDG-PET/CT and MRI in patients with head and neck cancer or CUP. Adding MRI to the diagnostic workup in occult cancer did not significantly improve detection of primary tumours. In case of malignant tumours, 50% were oropharyngeal cancer and required MRI for preoperative planning.
