Overview

Other diagnostic studies for hypopharyngeal cancer include barium swallow, which demonstrates irregular filling defects. Small sessile or superficially spreading lesions can be difficult or impossible to diagnose. Larger lesions may be visualized as irregular filling defects. Fluoro-D-glucose positron emission tomography may be performed to detect metastases of hypopharyngeal cancer.^[1]

Other Imaging Findings

Positron Emission Tomography

Fluoro-D-glucose positron emission tomography has an increasing role in diagnosis, staging and follow-up of head and neck malignancies, allowing identification of metabolically active tumor deposits. As is the case with FDG-PET elsewhere size is a limitation, as is movement artefact and presence of dental amalgam artefact.^[1]

Barium swallow

Other diagnostic studies for hypopharyngeal cancer include barium swallow, which demonstrates irregular filling defects. Small sessile or superficially spreading lesions can be difficult or impossible to diagnose. Larger lesions may be visualized as irregular filling defects.
