Overview

Other imaging findings for follicular thyroid cancer include radioiodine scan, which demonstrates increased uptake of radioactive iodine at the areas of metastases and laryngoscopy which demonstrates vocal cord immobility.

Key Findings in Radioiodine scan in Follicular Thyroid Cancer

• Metastases can be detected by radioiodine scan of the whole body as locations of increased uptake of radioactive iodine.

Key Examples of Radioiodine scan in Follicular Thyroid Cancer

Unstimulated I-131 scan of thyroid gland.

Key Findings in Laryngoscopy

• Laryngoscopy is a procedure in which the doctor checks the larynx (voice box) with a mirror or with a laryngoscope. A laryngoscope is a thin, tube-like instrument with a light and a lens for viewing. A thyroid tumor may press on vocal cords. The laryngoscopy is done to see if the vocal cords are moving normally.
• The findings in laryngoscopy are:

• Vocal cord immobility
• Air way compression
