  • Multiparameter perfusion imaging with leakage correction
    Patent number: 8670602
    Abstract: A magnetic resonance imaging (MRI) methodology is provided for simultaneous measurement of dynamic susceptibility contrast (DSC) MRI and dynamic contrast enhanced (DCE) MRI perfusion and permeability parameters using a combination of dual echo and spiral acquisition techniques with no contrast agent preload. T1 and T2/T2* leakage effects are eliminated, thereby permitting accurate measurement of blood volume, blood flow and vascular permeability which are used in evaluating tumor angiogenesis.
    Type: Grant
    Filed: May 22, 2008
    Date of Patent: March 11, 2014
    Assignee: Imaging Biometrics, LLC
    Inventors: Kathleen Schmainda, Eric S. Paulson, Douglas E. Prah

  • METHOD FOR DETECTING TUMOR CELL INVASION USING SHORT DIFFUSION TIMES
    Publication number: 20100298692
    Abstract: An improved method for detecting tumor cell invasion using diffusion times as short as two (2) msec incorporates diffusion weighing imaging techniques into a standard spin echo (SE) pulse sequence to minimize the effects of compartment boundary restrictions on diffusion values and corresponding MRI imaging data related to glioma invasion.
