20140321723 | Estimating Pharmacokinetic Parameters in Imaging - A method is provided for estimating a parameter of physiological significance. One or more images are provided of a tissue in a subject to whom a dose of a contrast agent (CA) has been administered, using a computer equipped with image processing software, the concentration or relative concentration of the agent in a region or regions of interest in the tissue is determined, thus generating concentration data. The time-based behavior of concentrations of CA within the tissue is determined using a pharmacokinetic model that is based on a set of pharmacokinetic model parameters. Using computer code, the pharmacokinetic model is fit to the concentration data, varying one or more parameters, such that a best fit estimate of a parameter of physiological significance is provided. | 10-30-2014 |
20150297160 | Estimating Pharmacokinetic Parameters in Imaging - A method of estimating a parameter of physiological significance in the central nervous system (CNS) is provided. The method comprises (a) providing one or more images of the brain or cerebral spinal fluid (CSF) in a subject to whom a dose of a contrast agent (CA) has been administered; (b) determining, using a computer equipped with image processing software, the concentration or relative concentration of the agent in a region or regions of interest in the brain or CSF, thereby generating concentration data; (c) describing the time-based behavior of concentrations of CA within the brain or CSF using a pharmacokinetic model that is based on a set of pharmacokinetic model parameters; and (d) fitting, using computer code, the pharmacokinetic model to the concentration data, varying one or more parameters, wherein the best fit estimates a parameter of physiological significance in the CNS. | 10-22-2015 |
