摘 要：The aim of this study was to collect the evidence on the performance of 2-deoxy-2-[^(18)F]fluoro-D-glucose(^(18)F-FDG)Positron Emission Tomography/Computed Tomography(PET/CT)in terms of detection rate(DR)and diagnostic accuracy in identifying hematogenous metastases in patients with differentiated thyroid cancer and compare its performance with that of other imaging techniques.A comprehensive PubMed/MEDLINE database research was carried out to retrieve studies documenting the performance of^(18)F-FDG PET/CT in depicting hematogenous metastases in patients with differentiated thyroid *** analysis was performed on a per-patient and per-lesion *** literature search yielded 15 articles to be included in the systematic review.^(18)F-FDG PET/CT showed a pooled DR of 85.08%on a per-patient analysis and 89.70%on a per-lesion *** bone lesions,a high DR(81.78%)was found for^(18)F-FDG PET/*** the sub-group analysis of lung lesions,pooled DR was 92.77%for^(18)F-FDG PET/CT,95.02%for CT,and 64.93%for magnetic resonance imaging(MRI).On a per-patient analysis,^(18)F-FDG PET/CT demonstrated a pooled sensitivity(SS)of 87.3%[95%confidence interval(CI):77.3%-94%]and a pooled specificity(SP)of 95.6%(95%CI:87.6-99.1).On a per-lesion analysis(328 metastases),PET/CT showed a pooled SS and SP of 86.3%(95%CI:73.5%-93.5%)and 93.4%(95%CI:71.7%-98.8%)in the detection of hematogenous *** presented systematic review and meta-analysis favor the use of^(18)F-FDG PET/CT in the detection of hematogenous metastases in patients with differentiated thyroid *** limited literature warrants further studies to confirm our findings.
