we report a 75 year - old man who presented with a cervical mass, dysphagia anil hoarseness, ct - xcan of neck showed a large cold nodule in the right lobe of thyroid gland, which was followed by surgical excision and its histopathologic exam revealed well-differentiated chondrosarcoma.
Administration of a precise amount of activity in thyroid gland radioiodine (¹³¹I) therapy is of prime importance. Several methods for this purpose have been suggested and used over many years. In this paper, a method for required ¹³¹I activity calculation for each case has been proposed. Major factors affecting ¹³¹I calculation such as gland volume, integral dose, and prescription index have b...
BACKGROUND AND PURPOSE Although radiation induced damage to the salivary gland is a known complication of radioactive iodine ((131)I) therapy for thyroid carcinoma, prediction of the severity and reversibility of sialoadenitis is difficult. Our aim was to correlate the extent of salivary dysfunction assessed by salivary gland scintigraphy with changes in the volume and attenuation of salivary g...

Background: The kidney has an important role in the metabolism of thyroid hormones. Impaired renal function and the resulting accumulation of uremic toxins may disturb thyroid physiology at various levels. The prevalence of goiter and thyroid nodules is significantly increased in patients with ESRD compared with other hospitalized patients admitted for treatment of non-renal disease. The purpos...
In this study, the MCNPX code version 2.6 has been used to simulate a proton therapy in thyroid gland. The neck phantom is cylindrical including skin, adipose, skeletal muscle and thyroid gland. Radiation source is close to the skin surface and single energy protons are collided perpendicular to the skin surface. The results of the simulation shows that the best proton energy interval, to cover...
The present study was designed to find out the difference in volume of the thyroid gland of Bangladeshi people in relation to age and sex and to compare with previous local and foreign studies. It was a Cross-sectional descriptive type of study. The hospital based study was conducted in the Department of Anatomy, Dhaka Medical College, Dhaka, from January to December 2008. The present study was...
I131 is a famous radio-iodine isotope in use for diagnosis and treatment of hyper functioning and cancerous thyroid gland. It is a nuclear reactor product; however nuclear reactor may be unavailable in some areas. Replacement by I-124 may be possible, another iodine isotope producible by cyclotron; a system more available than reactor. Here absorbed fraction of Gamma and Beta rays of...
To the Editors, A 67yearold woman presented with a solitary nodule in the left lobe of the thyroid gland. She was clinically and chemically euthyroid. Thyroid function test showed serum free thyroxine 1.01 ng/dl (normal 0.83–1.44 ng/dl), free triiodothyronine 1.91 pg/ml (normal 1.733.20 pg/m) and thyrotropin 1.25 mIU/L (normal 0.494.67 mIU/L). An ultrasound examination of thyroid gland show...
