Role of PET/CT in detection of post-Thyroidectomy recurrence in differentiated thyroid cancer patients with negative iodine radio-isotope scan & elevated serum thyroglobulin level

Abstract

Thyroid cancer accounts for approximately 1% of all cancer cases (Lin et al., 2012). Differentiated thyroid cancer is generally characterized by long term survival, good prognosis and low aggressiveness. Distant metastases is relatively rare with incidence ranging from 4- 27% (Bertagna et al., 2012). Most people diagnosed with thyroid cancer have a total thyroidectomy followed by radio-active iodine ablation. After treatment has finished patients will have regular check-ups. At some visits, patients may have blood tests, US, CT, MRI and scans (Hamed et al., 2014).
