A method and device for determining cerebral ischemia characteristics based on diffusion-weighted magnetic resonance imaging, the method comprising: according to the diffusion-weighted magnetic resonance imaging of a patient to be imaged, determining a cerebral ischemia area of the patient to be imaged, the cerebral ischemia area comprising a core area and a transition area; according to the apparent diffusion coefficient (ADC) values of the core area and the transition area, determining a DWI grayscale distribution parameter in an area with a low ADC value in the diffusion-weighted magnetic resonance imaging; and according to the DWI grayscale distribution parameter in the area with the low ADC value in the diffusion-weighted magnetic resonance imaging, determining whether the DWI in the area with the low ADC value in the diffusion-weighted magnetic resonance imaging mismatches the ADC value of the area with the low ADC value in the diffusion-weighted magnetic resonance imaging. The method enables a more scientific and objective decision to be made about whether thrombolysis is required for a patient with cerebral ischemia, thus improving the cure rate of the patients with cerebral ischemia.
