摘要

To investigate the pathological changes of canine brain after irradiation and evaluate the effect of diffusion-weighted imaging (DWI), 25 healthy dogs were treated with 70 Gy 60Coγ-ray irradiation on right temporal brain. Respectively, the apparent diffusion coefficient (ADC) values of canine alba and ectocinerea were measured by MRI T1 weighted imaging (T1WI), T2 weighted imaging (T2WI), and DWI. Compared with the control group, at every time point after irradiation, the ADC values of canine brain tissue were decreased significantly (P05). DWI is a very sensitive imaging technology that detects the changes of water molecule diffusion and microscopic pathological changes after canine brain irradiation.
