Lessons from the Tc-99m shortage: implications of substituting Tl-201 for Tc-99m single-photon emission computed tomography.
BACKGROUND In 2009, the Chalk River nuclear reactor closed for repairs that led to a critical shortage of technetium-99m (Tc-99m). Several centers used thallium-201 (Tl-201) as an alternative radiotracer for myocardial perfusion imaging. Because Tl-201 is considered by many as a suboptimal radiotracer, we sought to understand the impact of using Tl-201 (during the Tc-99m shortage) on downstream...
متن کاملComparison of Tc-99m Ethylenedicysteine (Tc-99m EC) with Tc-99m DPTA in evaluation of renal disease [Persian]
Tc-99m-EC is a new renal radiopharmaceutical introduced as an alternative for Tc-99m MAG3. Twenty-three normal volunteers and patients in different .stages of renal disease were evaluated with Te-99m EC and Tc-99m DTPA. The mean initial uptake of EC was significantly higher as compared to DTPA. There was a high correlation between rectangular and hand-drawn ROls for kidney and background,...
متن کاملComparison of Tc-99m MDP, Tc-99m HSA and Tc-99m HIG uptake in rheumatoid arthritis and its variants.
Tc-99m polyclonal immunoglobulin-G has been shown to be a successful agent in the depiction of active inflammation in rheumatoid arthritis (RA). The objective of this study was to compare the uptake behaviors of Tc-99m HIG and Tc-99m MDP in RA and variants of rheumatoid arthritis (VRA). Seventeen patients with RA and 8 patients with VRA presenting with active inflammation were included in this ...
متن کاملDiscordant uptake of Tc-99m PMT and Tc-99m GSA by two hepatocellular carcinoma lesions.
Tc-99m PMT and Tc-99m GSA can be taken up by hepatocellular carcinoma (HCC), but there has been no report concerning HCC showing accumulation of both of Tc-99m PMT and Tc-99m GSA. In this paper we describe a case of two simultaneously developed HCCs, one of which took up both tracers but the other took up neither of them.
متن کاملRole of Tc-99m MIBI and Tc-99m DMSA-V in Evaluation of Bone Tumors
Background: Bone sarcomas are usually aggressive tumors treated by multimodality approaches. Early detection of residual or recurrent tumor tissue after treatment is important in the management of these patients. This is currently achieved by clinical examination, diagnostic radiological procedures, radionuclide imaging techniques and detailed histological examination. Tumor response to preoper...
