Radioactive iodine has proved itself a most useful tool in the assessment of thyroid function and since its introduction in 1938 by Hertz, Roberts, and Evans (1) a voluminous literature on this subject has developed, much of which has been well summarized by Skanse (2) in his monograph. Although various workers have noted that there is a delayed excretion of the isotope in renal disease which p...

Introduction: Various iodine isotopes are undergoing radioactive decay except Iodine-127 (I-127. Iodine I-131 is unsealed radioactive material used in nuclear medicine for both diagnostic and therapeutic procedures in Royal Hospital since 2006. In radiotoxic classification, I-131 is in group 2 element. I-131 is highly reactive element due to its volatilization nature. Currently...

introduction: during the angiography of coronary vessels a great amount of  iodine mixed with radio-contrasts enter the body, and if autonomic centers exist in thyroid it causes hyperthyroidism. this can be dangerous in patients with cronary artery disease (cad). this study aimed to determine the effect of a radio-contrast used in coronary angiohraphy on thyroid’s function in patients referring...

Nuclear medicine would be greatly aided if compounds were available to promote the excretion of unwanted radioisotopes from biological systems. Such preparations would make possible greater use of long-lived radionuclides in medicine and would reduce some of the environmental hazards associated with nuclear energy. The biochemistry of radioisotope excretion is complicated because there are so m...

introduction: patients administered with a therapeutic dose of 131i for thyroid cancer treatment are potential sources of unacceptably high radiation exposure to other individuals, particularly the patient's immediate family members. the aim of this study is to investigate effects of early liothyronine consumption after radio-iodine therapy on accumulated dose and exposure rate in patients with...

A total of 10 volunteers were monitored for radiation doses, whose spouses were given radio-iodine (131I) orally. Nine of the spouses were given radio-iodine for Graves' disease and one for thyroid carcinoma. It was found that the highest radiation dose received by the volunteer was only 13.5% of the annual dose limit for individual members of the public. Hence, patients treated with radio-iodi...

introduction: differentiated thyroid carcinoma (dtc) is associated with excellent prognosis and high survival rates. this study was conducted to evaluate the influence of baseline and treatment-related factors on the health related quality of life (qol) in cured dtc. methods:this study was an analytic cross-sectional study on radio-iodine (rai) treated dtc patients during 2011-2012. the data on...
