Unilateral breast uptake of Tc-99m pertechnetate in a patient with cold nodule of the thyroid

Solitary Fibrous Tumor of Neck Mimicking Cold Thyroid Nodule in 99m Tc Thyroid Scintigraphy

A 68-year-old man had a rapidly growing, painless neck mass, thought to be nodular goiter. Ultrasonography showed a giant, heterogeneous mass occupying the middle and superior poles and protruding outside of the left thyroid lobe. The results of the thyroid function tests were normal. Thyroid scintigraphy revealed a large hypoactive nodule in the left thyroid lobe. Complete surgical removal of ...

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...

Unilateral breast uptake of 99mTc-pertechnetate.

Tc-99m-Pertechnetate in evaluation of meckel's diverticulum [Persian]

Meckel's diverticulum is a common congenital disorder which may result in Gl bleeding. For definite diagnosis before surgery, radiographic procedures such as small intestine barium studies are not greatly successful; on the other hand Tc-99m-Pertechnetate imaging is a physiologic and noninvasive method with high sensitivity and specificity. In this report, three patients with rectorrhagia...

Analysis of the factors associated with Tc-99m pertechnetate uptake in thyrotoxicosis and graves' disease.

To determine the factors associated with 20 minute Tc-99m pertechnetate thyroid uptake, we examined all patients in whom thyrotoxicosis was diagnosed at Chiba-Hokusoh Hospital, Nippon Medical School from 2001 April through 2003 March. Patients with thyrotoxicosis diagnosed during this period were 57 with Graves' disease (76%), 11 with transient hyperthyroxinemia (TH)(14.7%), and 7 with subacute...
