Other Imaging Findings
- Endoscopy is the use of a thin, lighted tube called an endoscope to examine areas inside the body. The type of endoscope the doctor uses depends on the area being examined. For example, a laryngoscope is inserted through the mouth to view the larynx; an esophagoscope is inserted through the mouth to examine the esophagus; and a nasopharyngoscope is inserted through the nose so the doctor can see the nasal cavity and nasopharynx.
- PET scan uses sugar that is modified in a specific way so it is absorbed by cancer cells and appears as dark areas on the scan.
