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...
متن کاملInaccuracy 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 کاملQuantitative single-photon emission computed tomography/computed tomography for technetium pertechnetate thyroid uptake measurement
OBJECTIVES Technetium pertechnetate (TcO4) is a radioactive tracer used to assess thyroid function by thyroid uptake system (TUS). However, the TUS often fails to deliver accurate measurements of the percent of thyroid uptake (%thyroid uptake) of TcO4. Here, we investigated the usefulness of quantitative single-photon emission computed tomography/computed tomography (SPECT/CT) after injection o...
متن کاملThyroid blood flow and uptake of technetium-99m pertechnetate in Graves' disease.
The aim of this study was to assess the relation of early thyroid blood flow (EBF) and technetium-99m pertechnetate ((99m)TcO(-)(4)) uptake, as an early diagnostic index in patients with Graves' disease (GD) by dynamic thyroid scintigraphy (40 frames, 3 sec/frame). Thirty patients with GD with mean age 50.0 +/- 9.0 y, range: 35.0-69.0 y, were studied. The results obtained were compared with tho...
متن کاملTechnetium-99m pertechnetate uptake in ectopic parathyroid adenoma.
A 37-year-old male with a persistent increased parathyroid hormone level, after subtotal thyroidectomy and parathyroidectomy, was referred for scintigraphic localization of a possible ectopic parathyroid adenoma. Tc-99m pertechnetate and Tc-99m MIBI scintigraphy were performed on separate days. There was marked uptake of both tracers in the mediastinum, which at surgery was confirmed to be an e...
