Aphasia was present in 19.4% of the men and 22.5% of the women in the Stroke Data Bank. There were no gender differences in aphasia incidence among the intracerebral hemorrhages. Aphasia was more frequent among women with infarcts (37.0%) than men (28.3%). When stroke mechanism was controlled for, there was an excess of aphasia among the women with stroke(More)
OBJECTIVES We produced hematoxylin and eosin (H&E) staining-like color images by using confocal laser scanning microscopy (CLSM), which can obtain the same or more information in comparison to conventional tissue staining. METHODS We improved images by using several image converting techniques, including morphological methods, color space conversion(More)
PURPOSE To validate a new objective digital image analysis technique to evaluate corneal staining. METHODS One hundred photographs of corneal staining from various ocular surface diseases in 100 patients were quantified by a new strategy: a combination of the difference of Gaussians (DoG) edge detection for morphologic properties of corneal erosions and(More)
The computer-aided detection (CAD) systems have been developed to help radiologists with the early detection of breast cancer. This system provides objective and accurate information to reduce the misdiagnosis of the disease. In mammography, the pectoral muscle region is used as an index to compare the symmetry between the left and right images in the(More)
BACKGROUND Factors that promote normalization of middle cerebral artery (MCA) velocities after cerebral aneurysm surgery may be important to identify in order to optimize management. Survival analysis of serial transcranial Doppler (TCD) MCA velocities in the setting of aneurysm surgery offers an additional means of analyzing outcome. METHODS We(More)
