| Abstract: | A photochemical reaction model of focal cerebral ischemic injury of rat was demonstrated by means of enhancedT 2-weighted magnetic resonance imaging. The cerebral ischemia model was made using vein injection of rose bengal and irradiation by a beam of a cw laser with the wave-length of 514 nm. The ischemic injury region in rat brain can be found clearly in theT 2-weighted magnetic resonance images in one hour, this time was calculated from the beginning of the laser irradiation to the end of the NMR data acquisition. It suggests thatT 2-weighted imaging can find cerebral ischemia earlier than several hours after the onset of ischemia given in other papers. It also confirms that theT 2-weighted magnetic resonance imaging approach should be of great potential to be applied in studying the cerebral ischemia. |
