Objective To examine the imaging changes of brain follwing local cerebral ischemia induced by photochemistry in the rat. Methods Rose bengal was injected through the tain vein. The brain was irradiated with yellow laser light through the intact skull. Magnetic resonance T2WI was examined. Results Ischemic focus in brain was found within 1h after irradiation. The images and positions were clear. Conclusion T2WI was a sensitive method to detect the early changes in brain ischemia.
