Agreement between Thyroid Uptake of 99mTc Pertechnetate and 131I in Hyperthyroid Patients

Extrathyroidal uptake from thyroid carcinoma on 99mTc-pertechnetate scintigraphy.

Three cases of imaging with 99mTc-pertechnetate (99mTcO4) and unusual positive lymph node uptake in the neck are reported hereby. Two cases were later diagnosed to be well-differentiated thyroid carcinoma, (DTC) with nodal metastasis. The third was a confirmed case of carcinoma thyroid that had presented with mass in the neck soon after surgery, being prepared for ablative dose of radioactive i...

Unilateral breast uptake of 99mTc-pertechnetate.

99mTc-pertechnetate for measuring thyroid suppressibility.

99mTc-pertechnetate-avid metastases from differentiated thyroid cancer are prone to benefit from 131I therapy

The aim of this study is to determine the contribution of neck and chest Tc-pertechnetate scan to the management of postoperative patients with suspicious metastatic differentiated thyroid cancer (DTC), particularly to the prediction of response to radioiodine (I) therapy. Just before I administration, a total of 184 postoperative DTC patients with stimulated serum thyroglobulin (ssTg) >10 ng/m...

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...
