Problems solved by technology

However, due to the characteristics of the human brain, the DWI and ADC are not evenly distributed. This method of detection using a hard threshold is difficult to guarantee the accuracy of the detection results; moreover, this detection method cannot exclude certain non-ischemic but high DWI and ADC. Low ADC lesions, such as tumors

Abstract

The invention discloses a method and a device for detecting an infarction area, a storage medium and equipment. The method for detecting an infarction area comprises: obtaining a cerebral parenchyma tissue part in a magnetic resonance image; according to a set surface diffusion coefficient threshold value, obtaining an infarction candidate region from the parenchyma tissue part; obtaining an infarction confirmation area in which the ratio of a diffusion weighted imaging signal to a surface diffusion coefficient is higher than a set value in the parenchyma tissue part; determining a candidate communication area communicated with the infarction confirmation area in the infarction candidate areas; and determining a target infarction area according to the diffusion weighted imaging signal value in the candidate communication area. According to the invention, infarction detection in acute and super-acute stages can be carried out, the calculation speed is high, and tumors and infarction areas with high DWI values and low ADC values can be distinguished.

Description

technical field [0001] This specification relates to the technical field of medical equipment, and in particular to a method, device, storage medium and equipment for detecting an infarct region. Background technique [0002] In magnetic resonance imaging, diffusion-weighted imaging (DWI) and apparent diffusion coefficients (ADC) imaging are imaging methods that can reflect the particularity of water molecule diffusion. In the acute stage of cerebral infarction, due to arterial blockage, the blood diffusion movement is weakened, and the DWI shows obvious high signal intensity, while the ADC map shows obvious low signal intensity; as the disease progresses, the DWI high signal intensity gradually decreases, and the ADC map shows obvious low signal intensity gradually recovers . It can be seen that DWI and ADC have high application value in the diagnosis of acute cerebral infarction. [0003] In the related art, the infarct is usually detected through the ADC threshold, and ...
