Magnetic resonance blood vessel wall image analysis method and system and computer readable medium

Abstract

The invention discloses a magnetic resonance blood vessel wall image analysis method. The method comprises the steps: reading a 3D image; acquiring a bright blood sequence of the 3D image, and automatically extracting blood vessels based on a central line of the bright blood sequence; acquiring a black blood sequence of the 3D image, and registering the center line of the bright blood sequence tothe black blood sequence; reconstructing a whole blood vessel according to the center line of the black blood sequence; obtaining a reconstructed 2D cross section; building a new training model, and training the training model according to the reconstructed lumen and wall characteristics of the 2D cross section; and importing a given blood vessel wall image into the trained training model to predict a lumen and a vessel wall. The invention further discloses a magnetic resonance blood vessel wall image analysis system and a computer readable medium. The blood vessel is reconstructed by matchingthe center line of the bright blood sequence of the 3D image with the black blood sequence, then the characteristics of the lumen and the wall of the tube are automatically obtained through deep learning and learning of a large number of samples, the method does not need to seriously depend on experience of doctors any more, and the segmentation result can be efficiently and accurately obtained.

Description

technical field [0001] The present invention relates to the technical field of magnetic resonance imaging, in particular to a magnetic resonance blood vessel wall image analysis method, system and computer readable medium. Background technique [0002] Atherosclerosis (Atherosclerosis) is the main cause of cardiovascular diseases, and its main lesion is characterized by intima lipid deposition in certain parts of the artery, accompanied by the proliferation of smooth muscle cell nuclear fiber matrix components, and gradually develops into atherosclerosis Sclerotic plaque (atherosclerotic plaque), a part of the vulnerable plaque is easily separated from the blood vessel wall under the impact of blood flow, and leads to serious consequences such as occlusion of the lumen or rupture and bleeding of the vessel wall. Studying the early features of carotid atherosclerosis is of great significance for the prevention of cardiovascular diseases. [0003] Since the plaque occurs in t...

Problems solved by technology

This manual segmentation method is not an end-to-end method. From the collected 3D image to the 2D image reconstruction to the segmentation result, it is fragmented, which makes the doctor's diagnosis work cumbersome and complicated, inefficient, time-consuming and labor-intensive, and serious. Rely on the doctor's experience
