---------------------------------------------------------------------***--------------------------------------------------------------------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 relate the development of post-treatment hypothyroidism with the dose distribution within the thyroid gland in breast cancer (BC) patients treated with loco-regional radiotherapy (RT). METHODS AND MATERIALS In two groups of BC patients postoperatively irradiated by computer tomography (CT)-based RT, the individual dose distributions in the thyroid gland were compared with each othe...

PURPOSE To establish a multivariate normal tissue complication probability (NTCP) model for radiation-induced hypothyroidism. METHODS AND MATERIALS The thyroid-stimulating hormone (TSH) level of 105 patients treated with (chemo-) radiation therapy for head-and-neck cancer was prospectively measured during a median follow-up of 2.5 years. Hypothyroidism was defined as elevated serum TSH with d...

Objective: to compare the estimated thyroid volume, as determined by two-dimensional (2D) and three-dimensional (3D) ultrasonography, with real volume. Design: Descriptive Study Animals: A total of 7 mixed breed dogs Procedures: On 2D ultrasound, the thyroid volume is estimated by the ellipsoid equation and on 3D ultrasound; it is estimated by outlining the boundaries of the thyroid lobe in ...

OBJECTIVE To establish benchmarks and study some sonographic characteristics of the thyroid gland in a group of euthyroid children aged up to 5 years as compared with age-matched children with congenital hypothyroidism. MATERIALS AND METHODS Thirty-six children (17 female and 19 male) aged between 2 months and 5 years were divided into two groups - 23 euthyroid children and 13 children with c...

background: the thyroid gland absorbs nearly all the iodine in the blood, independently of its isotopic composition. when a large enough activity of radioactive iodine like 131i, 132i, 133i is taken into the body, it can destroy the healthy thyroid gland cells as well as the cancer’s cells. in fact, as it is well known, some isotopes of iodine are used not only for acquiring thyroid images but ...

Background: To compare thyroid volume , thyroid stimulating hormone (TSH) , Free T4  and  prevalence of thyroid nodules between obese and  non-obese subjects .Also,  association  between BMI  and insulin resistance status with various parameters of thyroid gland was evaluated. Methods: Fifty –two patients with obesity and 38 normal body mass index (BMI ) volunteers, aged 20-50 years , were enr...

BACKGROUND Hypothyroidism is a frequent late side effect of radiation therapy of the cervical region. Purpose of this work is to develop multivariate normal tissue complication probability (NTCP) models for radiation-induced hypothyroidism (RHT) and to compare them with already existing NTCP models for RHT. METHODS Fifty-three patients treated with sequential chemo-radiotherapy for Hodgkin's ...

OBJECTIVE The objective of this study was to determine the measurement of normal range of ultrasound (US) thyroid gland dimensions in school-aged children (6-16 years) in our environment and compared with what is obtained elsewhere. SETTING AND DESIGN A prospective ultrasound measurement study done in University of Benin Teaching Hospital Benin, Nigeria. MATERIALS AND METHODS A prospective ...

thermal ablation therapies for benign thyroid nodules have been introduced in recent years to avoid the complications of traditional methods such as surgery. despite the little complications and the reportedly acceptable efficacy of thermal ablation methods, quite few medical centers have sought the potential benefits of employing them. this paper provides an introduction to the literature, pri...
