Technetium-99m mercaptoalbumin as a potential substitute for technetium-99m labelled red blood cells

European Journal of Nuclear Medicine, 1993
Technetium-99m labelled red blood cells (99mTc-RBCs) are far superior to 99mTc-labelled human serum albumin (99mTc-HSA) for radionuclide ventriculography, but their labelling is more complex, time consuming and risk bearing (in vitro labelling) or suffers from interference by some medications (in vivo labelling).

Technetium-99m radiopharmaceuticals

1995
Technetium is a group VIIB transition element which has seven electrons beyond the noble gas electronic configuration. The other members of the group are manganese (Mn) and rhenium (Re); together they form a triad (Mn, Tc, Re). All three elements easily lose the seven electrons to yield the +7 oxidation state of permetallate anions (MnO− 4, TcO− 4, ReO−

Technetium-99m Pyridoxylideneglutamate (P.G.) Cholescintigraphy

Radiology, 1976
Technetium-99m P.G. cholescintigraphy was performed in 27 human volunteers and 81 patients referred for hepatobiliary tract disease. The gallbladder, biliary system, and gastrointestinal tract were well visualized in the normal patients and volunteers.

Reproducibility of technetium-99m ethylenedicysteine clearance

European Journal of Nuclear Medicine and Molecular Imaging, 1999
It 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 ...

Making Technetium-99m

Chemical & Engineering News Archive, 2012
The key medical isotope technetium-99m can be produced directly in hospital cyclotrons, rather than by extracting the isotope from material made in nuclear reactors, a team of Canadian researchers ...

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 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,

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
