[Experimental perfusion scintigraphy of the myocardium using 199Tl chloride]

The authors conducted phantom, pharmacokinetic and scintigraphic investigation of the radionuclide thallium-199. It was shown that the spectrum of x-rays permitted good imaging of the phantom on photon energy peaks of 72 keV using a scintillation camera with a standard high resolution collimator. The physiochemical and pharmacokinetic characteristics of the radionuclide give an opportunity to use it for perfusion scintigraphy of the myocardium.
