Study of the clinical features and brain imaging characteristics by MRI examination of 33 cerebral stroke patients, the author have had some results: - Clinical features: The rate of cerebral infarction was higher than the rate of cerebral hemorrhage (84.8 percent versus 15.2 percent). A group of over 60-year-old patients accounted for 54.5 percent. Ratio of male/female was 1.36/1. Common clinical symptoms were hemiparesis or hemiplegia (60,6 percent), dysarthria or aphasia (18.2 percent), headache (12.1 percent). The most of risk factor was hypertension (69.7 percent). - Brain MRI characteristics: The average time for ppatients taken MRI examination was 127.03 hours. There was no patient taken MRI in the 3 hours first. Areas of brain affected the most were temporal lobes (51.5 percent) and internal capsules (39.4 percent). Middle cerebral arteries (MCAs) (75.8 percent), m,ultifocal lesions (51.6 percent). Average volumes of lesions on T2W, DWl, FLAIR and T1W images were 4,4209 cm3, 6,1629 cm3, 5,1884 cm3 and 2, 6796 cm3, respectively. Volumes of lesions measured on FLAIR images were twice as they measured on T1W images. On cerebral infarction's patients, there were 78.6 percent cases got high or so signal intensity on T1W images and 100 percent cases got high !lignal intensity on T2W, FLAIR and DWl images. On cerebral hemorrhage patients, there were 80 percent cases got high or so signal intensity on T1W images, 60 percent cases got high signal intensity on T2W images and 66.7 percent cases got high signal intensity on FLAIR or DWl images. When patients were undergone symmetric hemiparesis or hemiplegia, there were 57.9 percent lesions located on internal capsules. When patients were undergone asymmetric hemiparesis or hemiplegia, there were 71.4 percent lesions located on cerebral cortex. When patients were undergoing hemiparesis or hemiplegia on the left, there were 92.9 percent lesions located on the cerebral tissue on the right. When patients were undergone dizziness or vertigo, there were 75 percent lesions located on cerebellum and 25 percent lesions located on the MCAs.
