  • Publication number: 20090036784
    Abstract: Hemodynamic parameters of an organ are determined by first estimating hemodynamic parameters for portions of an organ from time sequenced images of the portions obtained after injection of a contrast agent. For each of the portions, the accuracy of the estimated hemodynamic parameters is assessed based on at least one of (i) a relationship between extraction efficiency product (FE) and contrast distribution volume in interstitial space (Ve); (ii) a relationship between blood plasma space volume (Vp), FE, and Ve; and (iii) a value of contrast distribution volume (VD).

  • Patent number: 6898453
    Abstract: A method for determining tissue type includes quantitatively determining a tissue blood flow (TBF) by deconvoluting Q(t) and Ca(t), where Q(t) represents a curve of specific mass of contrast, and Ca(t) represents an arterial curve of contrast concentration, and quantitatively determining a tissue blood volume (TBV) by deconvoluting Q(t) and Ca(t). The method also includes quantitatively determining a tissue mean transit time (TMTT) by deconvoluting Q(t) and Ca(t), and quantitatively determining a tissue capillary permeability surface area product (TPS) by deconvoluting Q(t) and Ca(t). The method also includes determining a tissue type based on the TBF, the TBV, the TMTT, and the TPS.
