99mTc-Pertechnetate Neck Uptake in the Evaluation of Thyroid Function

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.

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...

What need is there for standardization of thyroid uptake or scintigraphy using 99mTc pertechnetate in thyroid disease diagnosis?
