Abstract
Objective To explore the application value of 3.0T magnetic resonance perfusion weighted imaging(PWI)in the rat late brain glioma model.Methods C6 glioma cells were injected stereotactically into the right caudate nucleus of 32 Wistar rats.In 3 weeks after inoculation,the conventional MRI and PWI were performed.The relative cerebral blood volume(rCBV)values were recorded and compared with the pathological results.Results The tumor formation in 30 inoculated rats were confirmed by the sub-sequent pathological examination,with the tumor formation rate of 100%.PWI showed that rCBV values of the brain glioma region and the contralateral mirror image brain tissue were 262.61±72.82 and 189.39±57.21,the difference between them was statisti-cally significant(P<0.05).Conclusion The rat late brain glioma model is suitable for the study on the blood volume of brain tumor tissues.关键词
