UNLABELLED We studied the scintigraphic and associated clinical characteristics of radioiodine breast uptake in nonbreastfeeding thyroid cancer patients undergoing routine whole-body radioiodine scanning. METHODS We performed a retrospective review of the radioiodine scans and medical records of 30 prospectively collected cases. RESULTS Twenty-three nonpregnant patients had discontinued bre...

The use of thyroid preparations to reduce the size of non-toxic goitres is well established, as is their use in differentiating between high 1311 uptake rates due to thyrotoxicosis and those occurring in non-toxic goitres (Greer and Smith, 1954; Werner and Spooner, 1955). It would seem reasonable to expect that the amount by which the thyroidal 1311 uptake can be suppressed by thyroid preparati...

In patients affected by differentiated thyroid cancer, the whole-body scan (WBS) with 131-radioiodine, especially when performed after a therapeutic activity of 131I, represents a sensitive procedure for detecting thyroid remnant and/or metastatic disease. Nevertheless, a wide spectrum of potentially pitfalls has been reported. Herein we describe a 63-year-old woman affected by follicular thyro...

Objective(s): In this study, we aimed to evaluate the efficacy of thyroid volume measurement using 99mTc pertechnetate single-photon emission computed tomography (SPECT) images, acquired by the standardized uptake value (SUV)-shape scheme designed by our expert team.Methods: A total of 18 consecutive patients with Graves’ disease (GD) were subjected to both ultrasonographic and 99mTc pertechnet...

The thyroid hormone/thyroxin-binding globulin (TBG) ratio and the free thyroid hormone index (FTI) were compared in 372 subjects classified according to age, sex, and biochemical and clinical findings. Age-related variations in thyroid function tests were investigated, as was the relationship between triiodothyronine uptake and TBG. Men, but not women, showed significant age-dependent changes i...

UNLABELLED Measurement of serum thyroglobulin (Tg) levels and I-131 whole body scintigraphy (WBS) are used in the follow-up of patients with differentiated thyroid cancer (DTC). This study was designed to evaluate the significance of persistent I-131 uptake in the thyroid bed in patients with DTC following surgery and/or radioactive iodine ablation. Tc-99m thyroid scintigraphy (TS) and I-131 th...

The aim of the present study was to evaluate the role of selenium (Se) on the thyroid uptake and retention of radioiodine ((131)I) and on the serum levels of thyroid hormones. Experimental rats were divided into four groups with 10 animals in each group viz: untreated controls, (131)II-treated, Se-treated and (131)I+Se-treated. Group II and Group IV animals were injected intraperitoneally with ...

OBJECTIVE To assess the prevalence and pathological nature of incidental focal thyroid uptake on (18)F-FDG (2-[(18)F]-fluoro-2-deoxy-D-glucose) PET (positron emission tomography) and examine the role of the maximum standardised uptake value (SUVmax) to differentiate benign from malignant thyroid pathology. MATERIAL AND METHODS (18)F-FDG PET reports were retrospectively reviewed. Incidental fo...

511 AYOUNG WOMAN with papillary thyroid cancer treated with total thyroidectomy, received an ablative dose (3000 MBq) of 131I. Thyroxine had been withdrawn for 4 weeks. A wholebody scan was performed 8 days after the ablative dose of 131I. The scan (Fig. 1) shows uptake in the thyroid bed caused by thyroid remnant, diffuse uptake in the liver, and uptake in both breasts. Post-131I therapy scans...
