METHOD AND APPARATUS FOR DETERMINING CHARACTERISTICS OF CEREBRAL ISCHEMIA BASED ON MAGNETIC RESONANCE DIFFUSION WEIGHTED IMAGING

摘要

The present invention disclose 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 a magnetic resonance diffusion weighted imaging of the patient, wherein the cerebral ischemia region comprises a core region and a transition region; determining a DWI gray scale distribution parameter in a region with low ADC values in the magnetic resonance diffusion weighted imaging according to the apparent diffusion coefficient ADC values of the core region and transition region; and judging whether the DWI in the region with low ADC values in the magnetic resonance diffusion weighted imaging and the ADC values in the region with low ADC values in the magnetic resonance diffusion weighted imaging are mismatched according to the DWI gray scale distribution parameter in the region with low ADC values in the magnetic resonance diffusion weighted imaging. 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.
