Organ Visualisation with Technetium 99m Preparations

The British Journal of Radiology, 1967
Abstract Selected examples are presented in this paper to illustrate the potentialities of the use of some of the 99mTc compounds for organ visualisation. Although no attempt has been made at clinical evaluation, the additional information which can be gained by this means is both useful and impressive to those familiar with the technique.

Noncardiac uptake of technetium-99m MIBI

Seminars in Nuclear Medicine, 1994
A 74-YEAR-OLD spanish-speaking Peruvian woman underwent total thyroidectomy with bilateral median neck dissection in 1977 for follicular thyroid carcinoma. This was followed by Iodine-131 (1311) ablation for remnant thyroid tissue. In 1987, a 131I whole-body scan and a computed tomography scan of the chest confirmed lung metastasis as well as ...

Sub-Millimeter Technetium-99m Calibration Sources

Molecular Imaging & Biology, 2002
Small animal radioscintigraphic imaging systems aim to achieve sub-millimeter resolution. At the present time, sub-millimeter calibration sources that can be placed at will within an imaged volume are not readily available. We have developed a method for producing technetium-99m (Tc-99m) sources in less than 15 minutes with readily available reagents ...

Technetium-99m-labeled liposomes to image experimental colitis in rabbits: comparison with technetium-99m-HMPAO-granulocytes and technetium-99m-HYNIC-IgG.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1998
Scintigraphic techniques are routinely used for the evaluation of the extent and severity of inflammatory bowel disease. Currently, the radiopharmaceutical of choice is 99mTc-hexamethyl propyleneamine oxime (HMPAO)-leukocytes. We studied the imaging potential of two recently developed 99mTc-labeled agents, polyethylene glycol (PEG)-coated liposomes and

Technetium-99m-human fibrinogen.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1976
Exogenous fibrinogen has been successfully labeled with 99mTc using a modified electrolytic method. The exact labeling mechanism has not been determined. Experimental data suggest that the labeling process of 99mTc-fibrinogen is quite similar to that of 99mTc-human serum albumin as reported earlier by Benjamin.

Technetium-99m Diphosphonate Retention in Hyperparathyroidism

Annals of Internal Medicine, 1980
Excerpt To the editor: Fogelman and colleagues (1) show increased total-body retention of technetium-99m diphosphonate in a small group of patients with primary hyperparathyroidism and equate this ...

Clinical experience with technetium 99m teboroxime

Seminars in Nuclear Medicine, 1991
Technetium 99m teboroxime is a boronic acid adduct of technetium dioxime complex, a neutral lipophilic technetium-containing myocardial perfusion imaging agent with high myocardial extraction, rapid myocardial washout, and entero-hepatic excretion. Early "redistribution" occurs, and, based on preliminary animal data, appears to be due to differential ...

Newer Technetium-99m Radiopharmaceuticals

1987
Just now, we are having the semicentenary of the discovery of the element 43, later on named “technetium” (1,2). In 1937, Perrier and Segre showed that radioactive isotopes of element 43 could be formed by neutron or deuteron bombardment of molybdenum. They investigated the activity in order to collect some information on the chemistry of 43.
