Thyroid uptake and scintigraphy using 99mTc pertechnetate: standardization in normal individuals

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

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...

Absent radiotracer uptake in thyroid gland in parathyroid scintigraphy with 99mTc-MIBI: A case report

Localization of 99mTc- hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI) by parathyroid adenomas is well known, and this warrants MIBI scan to evaluate suspected parathyroid adenoma in primary hyperparathyroidism. Typically, the radionuclide concentrates in both the thyroid gland and parathyroid adenoma in early images, and later on delayed images washes out slowly from the...
