[Evaluation of thallium-201 distribution in myocardial scintigraphies performed after exertion].
Various techniques are described for the electronic processing of myocardial scintigraphic images using 201Thallium taken at various intervals after muscular exertion. The techniques serve to improve image definition and contrast, making them more representative of the physiopathological reality. The advantages and limitations of certain computer techniques for the measurement of radioactive distribution in the left ventricular myocardium are also discussed. Using such techniques it is possible to obtain an objective and comparative assessment of successive images.
