Introduction: The present study was aimed to assess the diagnostic performance of the two imaging methods of 131I-metaiodobenzylguanidine (131I-MIBG) and 99mTc-hydrazinonicotinyl-Tyr3-Octreotide (99mTc-HYNIC-TOC) in diagnosis and localization of pheochromocytoma and neuroblastoma. Methods: This study ...

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...

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...

Differentiated thyroid carcinomas usually show good uptake and response to I-131 ablative treatment. In this study, 90 patients following near total thyroidectomy who were referred to our institute for I-131 therapy are retrospectively studied. The patients are divided in two groups. Group 1 revealed complete ablation after one dose of I-131. Group 2 needed more than one dose of I-131 for...
