Clinical implication of F-18 FDG PET/CT for differentiated thyroid cancer in patients with negative diagnostic iodine-123 scan and elevated thyroglobulin

Accuracy of positron emission tomography and positron emission tomography-CT in the detection of differentiated thyroid cancer recurrence with negative131I whole-body scan results: A meta-analysis

“…Here, 4 studies were included that were published after the Dong et al bibliographic search period . Additionally, the previous meta‐analysis included 4 publications that, although identified in the searches for this meta‐analysis, were excluded during the selection process because they did not meet the minimum quantitative criteria of population with DTC, have a follow‐up time of <12 months, or their gold standard was unclear …”

Role of Fluorine 18 Fluorodeoxyglucose (FDG) Positron Emission Tomography (PET)/Computed Tomography (CT) in Detection of Post-Thyroidectomy Recurrence in Differentiated Thyroid Cancer

“…The upsides of this combined system over PET alone have turned out to be self-evident. There is expanding confirmation to recommend that PET/CT includes corresponding data in in staging, re-staging and follow-up in postthyroidectomy patients, prompting changes in management plans (6) .…”

18F-FDG PET-CT in Unknown-Source of Elevated Serum Carcinoembryonic Antigen (CEA) Level

“…3 18 F-FDG PET-CT as a new and non-invasive functional imaging technique, it is possible to evaluate the degree of progression of the tumor in a comprehensive way with some anatomic localisation of the site of tumor. 4 At present, there are several researches where 18 F-FDG PET-CT is used in patients with elevated serum CEA after operation of various malignant tumors to monitor recurrence and metastasis, 5 but there are few reports on the studies on the unknown primary lesion.…”
