毒性情報
Adverse Effects
Possible reported adverse effects of Thallium-201, when used for scintigraphy, include severe allergic reactions and gastrointestinal disturbances. Mustafa Yildirim et al. have demonstrated possible genetic damages with thallium-201 scans for myocardial perfusion imaging. A study done to assess the effects of radiopharmaceuticals on testicular function showed a higher probability of ill-defined adverse effects with thallium-201 compared to Tc-99m. Besides these adverse effects, there are some limitations to thallium-201 scans.
Toxicity Summary
At a significantly higher dose than that used in routine imaging, thallium-201 can potentially cause hair loss, gastrointestinal hemorrhage, and neurological symptoms. Death reportedly results at concentrations of about 2.8mg/kg. The FDA has approved the use of Prussian Blue for the therapeutic removal of thallium-201. Lansoprazole has also been shown to be useful for this process, as demonstrated by studies done in mice and rabbits.
