Non-contrast enhanced magnetic resonance image recognition method, system and device and storage medium

The invention relates to the technical field of medical image processing, and discloses a non-contrast enhanced magnetic resonance image recognition method, system and device and a storage medium, and the method comprises the steps: obtaining a to-be-recognized magnetic resonance image; analyzing the magnetic resonance image to obtain a lumen stenosis position of the central vein and a blood vessel outer wall contour; measuring the thrombus diameter and the blood vessel outer diameter according to the lumen stenosis position and the blood vessel outer wall contour; calculating the absolute stenosis according to the thrombus diameter and the blood vessel outer diameter; and identifying the magnetic resonance image through the absolute stenosis to obtain an image identification result. By analyzing the magnetic resonance image, the thrombus position, range and iconography characteristics can be accurately positioned, and meanwhile, by calculating the absolute stenosis degree, the stenosis degree of the central
