A method to obt,ain the diffusion coefficients and free volume parameters from desorption data for organic liquids in polymer films is presented. The method c0nsist.s of fit,ting a numerical solution of the diffusion equation to experimental desorption data. Some problems that arise in the solution
## Abstract Quantifiable MRI perfusion studies using the contrast agent GdβDTPA require measurement or estimation of the tissue partition coefficient (Ξ») for tracer kinetic modeling. Radiotracer techniques were used to obtain regional Ξ» measurements from the left ventricles of five dogs. Measuremen
