Synopsis：This study aims to probe the role of the quantitative analysis of MR diffusion-weighted imaging in differentiating Cerebral Alveolar Echinococcosis (CAE) with Brain metastases (BM).There was significant difference of the mean ADC values and eADC values (P<0.05) of the solid region between CAE and BM. There was no significant difference of the mean ADC values (P＞0.05) between CAE and BM，but there was significant difference that of the eADC values (P<0.05). MR-DWI was valuable for making diagnosis and differential diagnosis of patients with CAE and BM. EADC values is better than the ADC values.
