Forty patients with DTC underwent both post-therapeutic 131I-WBS and PET-CT. PET-CT performed on a positron emission tomograph combined with a 16-slice computer tomograph. Post-therapeutic 131I-WBS performed during radioiodine therapy on the single-detector gamma camera.</p><p><bold>Results</bold>. Sensitivity in detecting of the tumor persistence for PET-CT was 84 %, for post-therapeutic 131I-WBS 66 % (р &gt;0.05). In 17 (42.5 %) patients additional PET-CT foci were found that negative on 131I-WBS, including 11 (27.5 %) cases of distant metastases. Fifteen percent of patients had metastatic foci visualized only on 131I-WBS, including 4 (10 %) cases of distant metastases. In 17 (44 %) patients tumor foci were identified by both methods. A high pre-ablative level of stimulated thyroglobulin was the only independent predictor of the presence of PET-CTpositive metastatic foci (p = 0.001).</p><p><bold>Conclusion.</bold> 18F-fluorodeoxyglucose PET-CT can be recommended during the first radioiodine therapy in differentiated thyroid cancer patients with a high risk progression group, as well as with suspected the tumor persistence in case of a high pre-ablation thyroglobulin level, to complete staging, improve the quality of management and ongoing risk stratification.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – сопоставление диагностических возможностей позитронной эмиссионной томографии (ПЭТ), совмещенной с компьютерной томографией (КТ), и сцинтиграфии всего тела (131I-СВТ) в завершении стадирования опухолевого процесса у больных дифференцированным раком щитовидной железы.</p><p><bold>Материалы и методы</bold>.
