A comprehensive method is described for quantification of the relative 3-dimensional
distribution of TI-201 in the myocardium, following stress and subsequent washout. The …

The purpose of this study was to develop and validate a method for quantifying the uptake,
redistribution, and washout of thallium-201 (201Tl) obtained with rotational tomography. This …

A comprehensive method is described for quantitation of the spatial distribution of TI-201 in
the myocardium and its changes with time. The method, applied here to 51 patients, uses …
