Abstract

The invention relates to an ischemic penumbra recognition method and equipment, an electronic device and a storage medium. The method comprises the steps: obtaining an ischemic region parameter map and an infarction region parameter map of the brain of a patient based on a perfusion image, performing false positive removal on the ischemic region parameter map and the infarction region parameter map to obtain an ischemic region mask and an infarction region mask, and determining the ischemic penumbra of the brain of the patient according to the ischemic region mask and the infarction region mask. Through application of the method and the equipment, the problem of relatively low accuracy of the ischemic penumbra obtained based on threshold segmentation in related technologies is solved, and the accuracy of identifying the ischemic penumbra is improved.

Description

technical field [0001] The present application relates to the technical field of medical images, and in particular, to a method, device, electronic device and storage medium for identifying the ischemic penumbra. Background technique [0002] Ischemic stroke is the most common type of stroke with high morbidity, disability, mortality and recurrence rates. The brain tissue cells of patients with ischemic stroke will experience the process from ischemia to infarction. Specifically, when there is insufficient blood flow supply, brain tissue cells will enter an ischemic state and retain only the most basic physiological functions. Then these cells will return to the normal state again, but if the brain tissue cells in the ischemic state do not receive blood supply for a long time, these cells will enter the infarct state, and even if the blood supply is restored, they will no longer be able to restore their function. . Usually the difference between the ischemic area and the i...
