Inaccuracy of Thyroid to Background Uptake Ratio in Evaluating Technetium-99m-pertechnetate Thyroid Uptake and Establishing an Improved Algorithm
Objective(s): The aim of this study was to explore the accuracy of thyroid to background uptake ratio (UR) in the evaluation of 99mTc-pertechnetate thyroid uptake (TcTU) and establishment of an improved algorithm. Methods: This study was conducted on the thyroid images of 322 patients with thyroid diseases and 67 controls. For the purpos...
متن کاملChanges in salivary gland function following radioiodine therapy of thyroid diseases: A comparison of high-dose therapy for thyroid cancer and low-dose therapy for benign thyroid disease
Introduction: High-dose radioactive iodine therapy in differentiated thyroid cancer (DTC) may adversely affect the salivary gland function. This study is aimed to evaluate the effect of radioactive iodine (RAI) with dose of 100 mCi in DTC patients compared to lower doses of less than 30 mCi in hyperthyroid cases. Methods: Fifty four patients (13 men and 41 women) age: 42.3±14.3 (21-71) years w...
متن کاملFollow-up of a case of subacute thyroiditis with uncommon thyroid (99m)Tc uptake.
Thyroidal 99mTc uptake in the acute thyrotoxic phase of subacute thyroiditis (SAT) is always inhibited. However, a patient with SAT had signs in the right-side thyroid gland with transient thyrotoxicosis and slightly high 99mTc uptake levels in the right lobe, low 99mTc uptake in the left lobe, and normal overall uptake. Histological examination showed cellular destruction and granulomatous inf...
متن کاملRelationship between Anti-Thyroid Peroxidase Antibody and Thyroid Function Test
Background: Anti-thyroid peroxidase antibody (anti-TPO antibody) is a member of thyroid autoantibodies which are important in inducing and also diagnosing autoimmune thyroid diseases. Thyroid autoimmunity can cause several forms of thyroiditis and abnormal thyroid functions, ranging from hypothyroidism to hyperthyroidism. Objective: To evaluate the relationship between serum levels of anti-TPO ...
متن کاملImaging of medullary thyroid carcinoma with Tc-99m (V) DMSA [Persian]
Twenty-one patients with medullary thyroid carcinoma were studied prospectively with Tc-99m (V) DMSA after surgery. Pentavalent DMSA scintigram demonstrated abnormal uptake in 13 and equivocal uptake in 6 patients. Finally, seven patients with surgical or other imaging documentation were selected for this paper. Most of these patients were asymptomatic. Six patients had hypercalcitonemia ...
