WebFor diffusion tests, the gas flowrate through a wetted filter is determined. For HydroCorr™ tests, the apparent water flowrate from compressing a pleated filter’s structure is determined. During a bubble point test, pressure decay measurements are taken at increasing applied transmembrane pressures to map the filter’s integrity profile. WebMedian ADCs were measured in these regions and in the whole brain and were compared (with a two-tailed Wilcoxon test) as a function of clinical outcome. Outcome was defined by both early eye opening in the 1st week after arrest (either spontaneously or in response to external stimuli) and 6-month modified Rankin scale score. down payment assistance in houston texas
