| Abstract: | Objective To study the differential diagnosis value of magnetic resonance imaging(MRI) plain scanning combined with diffusion weighted imaging(DWI) in induced benign and malignant rat breast lesions.Methods Fifty female Wistar rats were subjected to intragastric administration of 7,12-dimethyl-1,2-benzanthracene(DMBA) to induce breast tumors.The rats were examined by MRI T1WI,T2WI,fat-suppressed T2WI and DWI.After post-processing of the images,T1WI signal intensity(SIT1),T2WI signal intensity(SIT2),the maxi... |
