Overview

Other diagnostic studies for tongue cancer include bone scan and positron emission tomography.

Other Imaging Findings

Bone scan

Bone scan has no role in the evaluation of mandibular involvement by tumors, nor has it been considered useful in the patient's general survey for bony metastases.

Positron emission tomography-CT imaging

• The combination of positron emission tomography (PET) and CT is a new staging and diagnostic modality in the evaluation of the patient with head and neck cancer.

• PET scans are used to reveal cancer and to examine the effects of cancer therapy by categorizing biochemical changes in the cancer. A PET-CT scan enables physicians to more accurately diagnose and identify cancer and its extent. PET-CT imaging can be used as a diagnostic tool in the initial evaluation of the patient who presents for initial staging and also for evaluating response to treatment.
