  • Determination of physiological parameters of tissue from dynamic contrast-enhanced MR data
    Patent number: 10123721
    Abstract: A method of determining microvascular architecture is disclosed. Dynamic contrast-enhanced magnetic resonance data acquired from a contrast agent administered to at least a part of a subject to be examined. From the dynamic contrast-enhanced magnetic resonance data a leakage parameter (kep) and a dispersion parameter (k) are computed. Effects of both convective dispersion and extravasation kinetics of contrast agent are taken into account.
    Type: Grant
    Filed: March 27, 2014
    Date of Patent: November 13, 2018
    Assignee: KONINKLIJKE PHILIPS N.V.
    Inventors: Marcel Breeuwer, Massimo Mischi, Hessel Wijkstra
  • DETERMINATION OF PHYSIOLOGICAL PARAMETERS OF TISSUE FROM DYNAMIC CONTRAST-ENHANCED MR DATA

    Abstract: A method of determining microvascular architecture is disclosed. Dynamic contrast-enhanced magnetic resonance data acquired from a contrast agent administered to at least a part of a subject to be examined. From the dynamic contrast-enhanced magnetic resonance data a leakage parameter (kep) and a dispersion parameter (?) are computed. Effects of both convective dispersion and extravasation kinetics of contrast agent are taken into account.
