Validation of global and segmental left ventricular contractile function using gated planar technetium-99m sestamibi myocardial perfusion imaging [PDF]

, 1994
Objectives. The purpose of this study was to test the hypothesis that segmental wall motion analysis determined from gated planar technetium-99m sestamibi myocardial imaging is reproducible and agrees well with echocardiographic data.Background ...

TECHNETIUM-99m LABELLING OF AN ANNEXIN FRAGMENT USING THE 4 + 1 MIXED LIGAND CHELATE SYSTEM (Cap.7)

, 2007
The tridecapeptide AQVLRGTVTDFPG — an annexin fragment — was labelled with 99mTc using the 4 + 1 mixed ligand system, in which Tc(III) is coordinated by a monodentate isocyanide and the tetradentate tripodal ligand tris(2-mercaptoethyl)- amine (NS3 ...

Reduced uptake of the proliferation-seeking radiotracer technetium-99m-labelled pentavalent dimercaptosuccinic acid in a 47-year-old woman with severe breast epithelial hyperplasia taking ibuprofen: a case report

Journal of Medical Case Reports, 2010
Introduction Recent studies have reported a risk reduction in the progression of benign breast disease to breast carcinoma through COX-2 pathways. Case presentation We present a case of severe epithelial hyperplasia in a 47-year-old woman with increased ...

Absolute activity measurements of molybdenum 99 and 4π-γ ion chamber measurements of technetium 99m and of molybdenum 99 with ingrown technetium 99m. [PDF]

, 1967
The activity of molybdenum 99 freshly separated from technetium is absolutely measured to ± 1.8 per cent, by 4πв-γ coincidence counting. Internal conversion effects are allowed for and the completeness of the separation is checked from the growth rate of

^99mTc Labelling Strategies for the Development of Potential Nitroimidazolic Hypoxia Imaging Agents

Inorganics, 2019
Technetium-99m has a rich coordination chemistry that offers many possibilities in terms of oxidation states and donor atom sets. Modifications in the structure of the technetium complexes could be very useful for fine tuning the physicochemical and ...

From [^99mTc]pertechnetate to [^99mTc]sestamibi: Dissection of a Complex Reaction Sequence Using Radio-LC-MS

Molecules
[99mTc]sestamibi ([99mTc][Tc(MIBI)6]+; MIBI = 2-methoxybutylisonitrile) is a clinically established myocardial perfusion SPECT tracer. Its one-pot kit-based synthesis from [99mTc]pertechnetate ([99mTc][TcO4]−) is complex, involving a 6-oxidation state ...

Transglutaminase-mediated conjugation and nitride-technetium-99m labelling of a bis(thiosemicarbazone) bifunctional chelator

, 2018
An assessment study involving the use of the transglutaminase (TGase) conjugation method and the nitride-technetium-99m labelling on a bis(thiosemicarbazone) (BTS) bifunctional chelating agent is presented. The previously described chelator diacetyl-2-(N-
