Activity measurements of the radionuclide 99Tcm

چکیده
In 2013, a comparison of activity measurements of 99m Tc using the Transfer Instrument of the International Reference System (SIRTI) took place at the Institutul National de Cercetare Dezvoltare in Fizica si Inginerie Nucleara – "Horia Hulubei" (IFIN-HH, Romania). Ampoules containing about 21 kBq and 40 kBq of a 99m Tc solution were measured in the SIRTI for, respectively, one and three half-lives. The comparison, identifier BIPM.RI(II)-K4.Tc-99m, is linked to the BIPM.RI(II)-K1.Tc-99m comparison and the degrees of equivalence with the key comparison reference value and between the present IFIN-HH result, the other K4 participants and the six participants in the K1 comparison have been evaluated.

Labelled Stealth liposomes in experimental infection: an alternative to leukocyte scintigraphy?
Indium-111 (111In) and technetium-99m (99Tcm) Stealth liposomes were compared with 111In- and 99Tcm-labelled white blood cells (WBC) in experimental infection in a rabbit model. Preformed polyethylene glycol-coated liposomes and separated WBC were radiolabelled with either 111In-oxine or 99Tcm-hexamethylpropyleneamine oxime (99TcM-HMPAO). After the intravenous administration of one of the four ...

The clinical value of Technitium-99TCm leucocyte in detecting early post-operative infection of prosthetic vascular grafts, to and from the femoral artery involving groin dissection is assessed. Twenty-five patients underwent bypass procedure using either Dacron or PTFE grafts. 99TCm labeled leucocyte scans were undertaken between 6-8 days following the bypass procedure. Fourteen patients had n...
متن کاملDistribution of radionuclide in the forest soils (Western Ghats-India)
Background: The presence of radionuclides in the soil, measures need to be taken to minimize the radiation dose to humans. It is mostly gamma-emitting radionuclides that contribute to the radiation dose in long term behavior of these radionuclides in soil may determine the extent to which such countermeasures need to be applied. Materials and Methods: The activity concentration of these radionu...
متن کاملDetermination of 99Mo contamination in 99mTc elute obtained from 99Mo / 99mTc- generator
Background: 99mTc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from Mo-99/Tc-99m generators. Usually the generators are either supplied by the Iran Atomic Energy Agency or by private companies from foreign countries. In this study we have measured 99Mo contamination in 99mTc elute from different generators in a period of one year. Materials and...
متن کامل99TCm-HMPAO SPECT studies in traumatic intracerebral haematoma.
Traumatic intracerebral haematomas are a common neurosurgical emergency. Their management, particularly the role of surgical removal, is controversial. Deterioration often occurs late, and is unpredictable. Eight patients with traumatic intracerebral haematomas were admitted to the neurosurgical unit to monitor their clinical state. All were studied within 48 hours of admission with single phot...
