Finite crystallite size and strain in polycrystalline material led to broadening of the diffraction lines. By analyzing this broadening, it is possible to extract information on the microstructure of crystalline material. In this research, we obtained the microstructure of nanocrystalline CeO2 sample using synchrotron diffraction data, applying the whole powder pattern fitting and Williamson-Ha...
OBJECTIVES The primary aim of this study was to prospectively validate the predictive value of the ABCD²-I score and to then compare the predictive accuracy of the ABCD² score and ABCD²-I score for 1-year risk of stroke in admitted patients with transient ischemic attack (TIA) as defined by the World Health Organization (WHO) time-based criteria. METHODS Data were collected from patients with...
BACKGROUND AND PURPOSE Growth of the core infarct during the first hours of ischemia onset is not well-understood. We hypothesized that factors other than time from onset of ischemia contribute to core infarct volume as measured by MR imaging. MATERIALS AND METHODS Prospectively collected clinical and imaging data of consecutive patients with stroke presenting between March 2008 and April 201...
