Evaluation of thyroid nodules with technetium‐99m MIBI and technetium‐99m pertechnetate
Head & Neck, 2001AbstractBackgroundMost thyroid centers use fine‐needle aspiration (FNA) and technetium‐99m pertechnetate for the preoperative assessment of thyroid nodules. This approach is sufficient in most cases other than follicular neoplasm, and follicular carcinoma is more common than papillary carcinoma in developing countries such as in our center.

Adsorption of technetium-99m tetrofosmin and technetium-99m furifosmin on plastic syringes
European Journal of Nuclear Medicine and Molecular Imaging, 1998Some groups have reported that adsorption of radiopharmaceuticals on disposable plastic syringes can reach levels of almost 50%. This high loss of radioactivity stimulated us to carry out similar studies. Our measurements were done in combination with patient studies. Therefore, we used 2-ml syringes, all of the same brand.

Technetium 99m Sestamibi in Multiple Myeloma
Radiology, 2005Editor: We read with great interest the excellent review on diagnostic imaging in multiple myeloma by Dr Angtuaco and colleagues in the April 2004 issue of Radiology (1). We would like to address just a few issues related to the use of technetium 99m (Tc) sestamibi.

Technetium-99m-labeled monoclonal antibodies: influence of technetium-99m binding sites.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1994A number of 99mTc-labeled monoclonal antibodies (Mabs) are being evaluated for diagnostic applications. Preparations are carried out using both direct and indirect (bifunctional chelating agent, BFCA) labeling procedures in which nonspecific 99mTc binding has been postulated.By using the ascorbic acid (AA) reduction mediated direct labeling procedure ...

Thyroid imaging was performed using technetium-99m methoxyisobutylisonitrile and technetium-99m pertechnetate in 58 patients. The 99mTc-pertechnetate scans showed a total of 77 nodules: 60 cold, 13 hot and 4 of normal activity. There was no 99mTc-MIBI accumulation in 46.4% of 99mTc-pertechnetate cold nodules; 27 (45%) of these nodules showed 99mTc-MIBI

This study compared three radionuclide techniques in distinguishing musculoskeletal infection from noninfectious inflammation.Thirty-five orthopedic patients with suspected musculoskeletal infection were examined using three radionuclide techniques in sequence: triphasic bone scintigraphy, 99mTc radioleukocytes (99mTc-WBC) scintigraphy and 99mTc human ...

Technetium-99m Radiopharmaceuticals
2010The name technetium was derived by the scientist Mendeleyev from the Greek word technetos, meaning “artificial.” Technetium-99m was discovered in 1937 by Perrier and Segre in a sample of naturally occurring 98Mo irradiated by neutrons and deuterons. The first generator as a source for Tc-99m was introduced in 1957 at the Brookhaven National laboratory,

Reproducibility of technetium-99m ethylenedicysteine clearance
European Journal of Nuclear Medicine and Molecular Imaging, 1999It has been shown that technetium-99m ethylenedicysteine ((99m)Tc-EC) clearance displays a strong correlation with orthoiodohippurate clearance and that it is possible to estimate effective renal plasma flow from (99m)Tc-EC clearance. However, in routine practice, when monitoring renal function of patients by clearance determinations it is imperative ...
