Diffusion-weighted imaging (DWI) detects small changes in water diffusion that occur in ischemic brain. This study evaluated the clinical usefulness of a phase-navigated spin-echo DWI sequence compared with T2-weighted magnetic resonance imaging (T2W MRI) in patients with cerebral ischemia and assessed apparent diffusion coefficient (ADC) and T2-weighted(More)
An in-vitro study was conducted to assess wetting characteristic of four brands of addition silicon materials subjected to immersion disinfection using four different disinfectants. Among the non-disinfected specimens, the lowest contact angle was recorded for Aquasil ultra (21.63), followed by Imprint II (29.06), Aquasil LV (44.10) and Take 1 (44.55).(More)
BACKGROUND Disinfection of impression materials prevents cross-contamination; however, the disinfectants may alter the wettability property. The purpose of this investigation was to evaluate the wettability changes of polyether impression material after immersing in four different chemical disinfectant solutions for a period of 10 min and 30 min,(More)
