Studies ofradioguided surgery are examining the use of intraoperative positron emission tomography (PET) probes or gamma probes. The probes are used after the injection of a radionuclide to help find hidden areas of cancer or remaining thyroid tissue. These methods appear to help ensure complete removal of the thyroid. This may reduce the number of additional surgeries and will reduce the complications related to persistent disease (Surgery, PMID 20965536; Thyroid, PMID 20950253). Researchers are also studying radioguided surgery as a way to treat recurrent thyroid cancer (Otolaryngology – Head and Neck Surgery, PMID 21952355).
