Abstract

The present invention discloses a method and apparatus for determining characteristics of cerebral ischemia based on magnetic resonance diffusion weighted imaging, so as to provide a more objective basis for determining whether an acute cerebral ischemia patient should be treated with thrombolysis. The method comprises: determining a cerebral ischemia region of a patient based on magnetic resonance diffusion weighted imaging of the patient, wherein the cerebral ischemia region comprises a core region and a transition region; determining an apparent diffusion coefficient ADC characteristic parameter ADC_r in a region with high DWI values in the magnetic resonance diffusion weighted imaging according to diffusion weighted image DWI values in the core region and transition region; and judging whether ADC values in the region with high DWI values and the region with high DWI values are mismatched according to the ADC characteristic parameter ADC_r. The method according to embodiments of the present invention provides a more scientific and objective basis for making a decision on whether the acute cerebral ischemia patient should be treated with thrombolysis, thereby improving a cure rate of the cerebral ischemia patient.
