BACKGROUND The goal of iodine-131 therapy for pediatric Graves' disease is to induce hypothyroidism. However, changes in post-treatment thyroid volume have not been investigated in pediatric and/or adolescent patients. OBJECTIVE The aim of this retrospective study was to examine whether changes in thyroid volume predict post-treatment hypothyroidism in adolescent Graves' disease patients. P...

Background: Radiofrequency ablation (RFA) is a relatively new procedure for treating benign thyroid nodules. The purpose of this study was to evaluate the safety and efficacy of RFA for treating benign thyroid nodules so as to serve as a reference for future clinical practice. Methods: This study retrospectively analyzed the clinical data of patients receiving percutaneous RFA for treating thyr...

Among the factors that may influence thyroid size, pregnancy and its goitrogenic effect have been widely investigated, but thyroid volume and pregnancy have never been compared retrospectively, and there are no data on the possible relationship between thyroid size and parity. The purpose of this work was to evaluate the effects of pregnancy on thyroid volume in a moderate iodine deficiency are...

Objective. Thyroid volume measured by ultrasound to define goiter needs reliable local thyroid volume reference from iodine-sufficient populations. The aim of this study is to explore the reference interval for normal thyroid volume in schoolchildren aged 8-10 years from Zhejiang Province, China. Methods. A probability-proportionate-to-size sampling method was applied to select a representative...

The mammalian thyroid gland maintains basal metabolism in tissues for optimal function. Determining thyroid volume is important in assessing growth and involution. Volume estimation is also important in stereological studies. Direct measurements of colloid volume and nuclear-to-cytoplasmic ratio of the follicular cells may provide important information about thyroid gland function such as hormo...

This study aimed to establish a local reference of thyroid volume in Sudanese normal subjects using ultrasound. A total of 103 healthy subjects were studied, 28 (27.18%) females and 75 (72.82%) males. Thyroid volume was estimated using ellipsoid formula. The mean age and range of the subjects was 21.8 (19-29) years; the mean body mass index (BMI) was 22.3 (16.46-26.07) kg/m(2). The overall mean...

UNLABELLED The effect of radioiodine in the treatment of nontoxic goiter is seldom evaluated quantitatively. The aim of this study was threefold: (a) to assess the effect of 131I on goiter volume, (b) to establish a relationship between CT volume reduction and the amount of radioactivity taken up by the thyroid and (b) to assess the precision of scintigraphic thyroid volume measurements. METH...

Ahigher frequency of skewed X chromosome inactivation (XCI) is found in patients with autoimmune thyroid disease (AITD) than in controls. Although goitre is often present in AITD, a recent study failed to show an association between XCI and clinically overt nontoxic goitre. However, the etiology of overt goitre is complex, and the mechanisms influencing thyroid volume may involve fewer factors ...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract A complete solution to estimate the volume of the thyroid gland directly from ultrasound (US) images is proposed in this paper. Physicians usually diagnose the pathology of the thyroid gland by its volume. However, even if the thyroid glands are fo...

PURPOSE To validate the use of the ratio between the total transverse diameters of the thyroid lobes (Th) and the width of the trachea (Tr)-the Th:Tr or Yasumoto ratio-as a sonographic method for estimating thyroid size, and to determine reference values for this ratio and for thyroid volume in neonates. METHODS In this cross-sectional study, we evaluated thyroid size according to the Yasumot...
