  • Title: [Determination of the temporal characteristics of tracer transport in hemodynamics studies].
    Author: Vinogradov AV, Gel'fand IN, Sycheva IM, Rylova AK.
    Journal: Kardiologiia; 1983 Nov; 23(11):82-6. PubMed ID: 6228685.
    Abstract:
    A novel method designed for processing the findings obtained from radionuclide studies of hemodynamics is proposed. This technique is based on the establishment of the mean time needed for the transit of the indicator through the studied physiological structure which is done by determining its transport function. Temporal division of information concerning the right and left departments of the heart suggested by the authors for the preliminary processing of radiocardiographic data has a number of advantages over the current techniques. The application of the proposed method for interpreting radiocardiograms in 74 patients with compromised circulation showed that the determination of the mean time of the indicator transit whose magnitude alters significantly depending on the severity of the disease enables the objective evaluation of the state of the physiological system studied.
