چکیده
Hellenic Journal of Nuclear Medicine January April 2011 www.nuclmed.gr 2 Figures 2 and 3. 131I-SPET study (Fig. 2) further clarified these foci in both kidneys. 18F-FDG-PET scan (Fig. 3) done on a separate day revealed abnormal foci of 18F-FDG uptake in the lower poles of both kidneys, corresponding to the foci seen on post treatment 131I-SPET. In the 18F-FDG-PET image, the foci can be well visualized and appreciated in the coronal slice (arrows) while in the MIP image the relatively intense overlapping gut uptake obscures the pattern of uptake in the foci.

Value of Dedicated Head and Neck 18F-FDG PET/CT Protocol in Detecting Recurrent and Metastatic Lesions in Post-surgical Differentiated Thyroid Carcinoma Patients with High Serum Thyroglobulin Level and Negative 131I Whole-body Scan
Objective(s): In clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (DTC) patients with high serum thyroglobulin (Tg) and negative 131I whole-body scan (WBS) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. The purpose of this study was to evaluate the value of 18F-FDG PET/CT scan in DTC patients with high seru...

OBJECTIVE To assess whether FDG PET could localize the recurrent or metastatic lesions in papillary thyroid cancer patients with negative radioiodine scan. METHODS Whole body PET was performed after injecting 370-555 MBq of 18F-FDG in 108 patients, who were suspected of having recurrence or metastasis and whose 131I whole body scans were negative. Recurrence or metastasis occurred in 63 patie...

Anaplastic thyroid carcinoma is an uncommon, highly aggressive malignancy usually presenting in the elderly. An eighteen year old boy was recently diagnosed as anaplastic carcinoma of the thyroid. PET/CECT scan performed for staging, revealed a large FDG avid heterogeneously enhancing thyroid mass with bilateral jugular venous thrombosis, which also showed increase...
متن کاملDifferentiated Thyroid Carcinoma with Elevated Thyroglobulin and Negative Radioiodine Whole-Body Scan Metastases
Serum thyroglobulin (Tg) and Tg antibody (TgAb) levels, together with neck ultrasonography and 131I whole-body scintigraphy (WBS), are diagnostic tools for postoperative follow-up of patients with differentiated thyroid carcinoma (DTC). Generally, good correlation is seen between Tg and WBS in follow-up studies for DTC after thyroid remnant ablation. Undetectable serum Tg with negative WBS resu...

Objective: The aim of this study was to explore the clinical characteristics of renal metastatic cancer, the methods for its detection by radioiodine (131I), and the response to 131I treatment in fourteen patients with renal metastases from differentiated thyroid carcinoma (DTC). Subjects and methods: DTC patients (n = 2,955) that received treatment with 131I were retrospectively analyzed. Scan...
