a 38 years old male worker presented with an advanced left side retroperitoneal mass, with metastatic involvement of 11th thoracic vertebra (t11) and resultant paraparesia and paresthesia . the histopathologic examination and immunohistochemical analysis confirmed the diagnosis of paraganglioma. decompression laminectomy and fixation of involved vertebra resulted to considerable symptomatic rel...

In a recent report (1), List, Telegadas, and Ferber take issue with my earlier conclusion (2) that vented underground tests in Nevada were the probable sources for the repeated occurrences of iodine-131 fallout in midwestern United States during May 1962. In doing so they provide no evidence to establish that the underground shots in question were contained, but they suggest that precipitation ...

Post-treatment or diagnostic whole-body radioiodine scintigraphy is widely used to assess the residual, recurrence, or metastases of differentiated thyroid carcinoma because of the high sensitivity and accuracy that this assessment provides. While bearing in mind all the diagnostic potential of this test, we have to consider its’ potential pitfalls, as well. Herein, we present 4 patients with d...

Objective(s): 68Ga-DOTATATE positron emission tomography (PET)/computed tomography (CT) has shown promising results in imaging of neural crest tumors (NCT). Herein, we compared the performance of 68Ga-DOTATATE PET/CT and 131I-MIBG single photon emission computed tomography (SPECT)/CT in the initial diagnosis, staging and follow-up of pa...

Introduction: Retention of I-131 in the body of patients with differentiated thyroid carcinoma (DTC) has a direct effect on therapeutic outcome of radioiodine therapy. There are several factors that may influence retention time of radioiodine in the body of these patients. In this study we are going to assess effects of administered radioiodine activity, serum thyroid stimulati...

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 i-124 thro...

When I(131)-albumin is given intravenously to rabbits, the radioactive breakdown products that are released into the plasma and urine can be extracted into acetone. Paper chromatography and paper electrophoresis show that about 80 per cent of these are I(131)-iodide and the remainder are organic I(131)-iodine compounds. When I(131)-iodide is given to rabbits taking iodide in their drinking wate...
