Pyramidal lobe decreases endogenous TSH stimulation without impact on radio-iodine therapy outcome in patients with differentiated thyroid cancer.

Objectives: The aim of the study was to assess the frequency of pyramidal lobe (PL) detected in iodine-131 (I-131) scans of thyroid bed in patients after thyroidectomy for differentiated thyroid cancer (DTC) and to investigate influence of PL on endogenous thyrotropin (TSH) stimulation as well as on the effects of the radio-iodine ablation in one-year follow-up.

Patients And Methods: This study was designed as a retrospective analysis of 302 radio-iodine neck scans of patients thyroidectomized due to DTC. The study population was selected from patients with PL detected in thyroid bed scintigraphy.

Incidental ¹⁸F-FDG uptake in the thyroid in patients diagnosed with PET/CT for other malignancies.

Background: The value of PET/CT imaging in diagnosis of different cancers has been widely described. PET/CT may contribute to visualization of additional findings that were not the indication to the study and did not refer to initial diagnosis. In a small number of PET/CT scans an incidentally found focal ¹⁸F-FDG uptake in the thyroid gland is found.

89Sr versus 153Sm-EDTMP: comparison of treatment efficacy of painful bone metastases in prostate and breast carcinoma.

Background And Aim: Painful bone metastases are most frequent in patients with advanced prostate or breast carcinoma. The aim of this study was to compare the analgesic effect of radionuclide therapy using Sr and Sm-EDTMP in patients with painful bone metastases of these tumours.

Material And Methods: One hundred patients treated with radionuclide bone palliation therapy were analysed.

Increased uptake of technetium-99m methylene diphosphonate in muscles in the course of polymyositis.

A case of a woman aged 46 years with signs of rhabdomyolysis and acute renal failure is presented. Coxsackie serum test was positive. Increased uptake of Technetium-99m methylene diphosphonate (99mTc-MDP) by muscles of thighs and calves was observed.

Fractionated dosage of radioiodine for the ablation of differentiated thyroid carcinoma.

In some countries with a limited number of specialized hospital beds for radionuclide therapy, ablation therapy (RIT) of differentiated thyroid carcinoma (DTC) is performed using a fractionated dosage of radioiodine. The aim of this study was to evaluate the early clinical outcome of ablation with fractionated doses of RIT in comparison to the ablation with a single dose. A subset of 386 subjects with DTC referred for the initial RIT was selected retrospectively for the study.

[Usefulness of isotope diagnosis, ultrasound neck investigation and thyroglobulin assays in quantification of patients operated on for differentiated thyroid cancer and prepared for radioiodine treatment].

Unlabelled: The aim of the study was to assess the efficacy of surgical treatment of patients operated on differentiated thyroid carcinoma, using Tg serum assays and 131-I whole body scintigraphy. We investigated 208 patients aged from 15 to 78 yr. (mean 43.
