18‐FDG‐PET in the initial staging of sinonasal malignancy

Abstract

For diagnosis of sinonasal malignancy, PET scans have a high sensitivity, although false negatives occurred in 6% of cases. PET scanning detected metastasis in 31% of patients, but SUV max did not function as a marker for clinically advanced disease. The role of diagnostic PET for sinonasal malignancy is currently limited to cases with a high suspicion of metastatic disease.
