Abstract

The invention discloses a carotid artery stenosis degree calculation method and device and a storage medium, and the method comprises the steps: S1, receiving a neck MRA image, and carrying out the interlayer registration of a first sequence and a second sequence in the neck MRA image, so as to form an interlayer corresponding relation; S2, transverse blood vessels are extracted from all layers ofimages of the registered first sequence, and the blood vessel area of each transverse blood vessel is calculated; S3, extracting a transverse blood target from each layer of image of the registered second sequence, and calculating the blood area of each transverse blood target; S4, according to the interlayer corresponding relation, the blood vessel area of each transverse position blood vessel and the blood area of each corresponding transverse position blood target are substituted into a calculation formula, and a plurality of carotid artery stenosis degrees are obtained through calculation; and S5, outputting the maximum value in the plurality of carotid artery stenosis degrees as the carotid artery stenosis degree of the neck MRA image. According to the embodiment of the invention, the carotid artery stenosis degree can be automatically calculated, so that the diagnosis efficiency and accuracy of doctors are improved.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a method, device and storage medium for calculating the degree of carotid artery stenosis. Background technique [0002] The "China Stroke Prevention Report 2017" released in 2017 pointed out that the incidence of stroke in China is one of the highest in the world. The number of people over 40 years old in my country who are currently suffering from or have suffered from stroke is estimated to be 12.42 million, and the proportion of stroke caused by carotid artery stenosis is relatively high. Carotid artery stenosis is mostly caused by plaque, and if it is not diagnosed and treated in time, it will lead to serious consequences. [0003] In the diagnosis of carotid artery stenosis caused by plaque, MRA (Magnetic Resonance Angiography) nuclear magnetic resonance imaging technology is one of the more commonly used methods. The patient's condition was well diagnose...
