Identifying Tumor Vascular Permeability Heterogeneity Using Reduced Encoding Techniques
"In our model, female Sprague Dawley rats with N-ethyl-N-nitrosourea (ENU) induced mammary tumors imaged with fast T1-weighted gradient echo DCE MRI following a Gd-DTPA injection, there is a window of resolutions that detects similar PS ""hot spots"" compared to those obtained from the clinical …

Understanding The Factors Influencing Contaminant Attenuation And Plume Persistence
… include incomplete isolation of the source zone, permeability heterogeneity, well-field hydraulics, and non-ideal (rate-limited, nonlinear) desorption. However, the significance of each factor, especially the site-specific contribution is undetermined, which is very important for site development …

Multi-scale Investigations of Geological Carbon Sequestration in Deep Saline Aquifers
… However, our understanding on the wettability heterogeneity of a natural rock and its effect on multiphase fluid flow in a natural rock is limited. This work innovatively models the heterogeneous wettability of a rock as a correlated random field. The realistic wetting condition of a natural …

NMR studies of carbon dioxide sequestration in porous media
… to capillary trapping, the effect of vertical permeability heterogeneity, such as is often present in underground rock formations, was investigated for the flow of miscible (water/brine) gravity currents in model porous media (glass bead packs), using MRI techniques such as 2D spin-echo imaging …
