Uptake of technetium 99m MDP by hepatoblastoma

European Journal of Nuclear Medicine, 1987
Focal uptake of 99mTc-MDP was seen in a case of hepatoblastoma. The focal uptake corresponded to an area of calcification on CT, which was shown histologically to consist of osteoid with mineralization. The mechanism of uptake by the tumor in this case is likely to be the same as for skeletal uptake.

Technetium-99m Radiopharmaceuticals

2010
The 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,

Excretion of technetium 99m hexakismethoxyisobutylisonitrile in milk

European Journal of Nuclear Medicine, 1991
The amount of radioactivity excreted in breast milk following the administration of technetium 99m hexakismethoxyisobutylisonitrile (99mTc-MIBI) to a patient referred for cold spot myocardial scintigraphy was determined. During the first 24 h after administration, only 41.2 kBq 99mTc (0.0084% of the injected dose) was excreted in 448 ml milk with the ...

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.

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

The Radiopharmaceutical Chemistry of Technetium-99m

2019
Technetium-99m (99mTc) is a radiometal that has nearly ideal nuclear properties for diagnostic nuclear medicine imaging, which has helped make it high impact and extensively utilized radionuclide in medicine. 99mTc-based imaging—which can be done using a simple gamma camera or a more advanced 3-D method known as single photon emission computed ...

Technetium-99m chelates as radiopharmaceuticals

1996
Technetium-99m (99mTc) is currently, and will be in the foreseeable future, the most widely used radionuclide used in virtually all clinical diagnostic Nuclear Medicine laboratories in the world. Several 99mTc radiopharmaceuticals that are routinely used have become important factors in decisions on the diagnosis and treatment of patients with a ...

Comparison of technetium-99m-MDP, technetium-99m-WBC and technetium-99m-HIG in musculoskeletal inflammation.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1998
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 ...
