  • Cell size imaging
    Patent number: 9747490
    Abstract: In the various embodiments, cell size imaging is performed using a method that relies upon the acquisition of gradient echo and spin echo data during contrast agent (CA) passage through tissue and estimation of “perturber” size using the ratio of ?R2* and ?R2. When measured at CA equilibrium, the magnetic field perturbations, and associated MRI signal changes, are determined by the cellular features and not the vasculature. Thus, in cell size imaging the cells act as the perturbers.
    Type: Grant
    Filed: November 4, 2015
    Date of Patent: August 29, 2017
    Assignee: VANDERBILT UNIVERSITY
