The invention provides a magnetic resonance imaging and plaque identification method and device, and the method comprises the steps: obtaining magnetic resonance undersampling K space data; transforming the magnetic resonance under-sampling K space data into an image domain to obtain a pre-processed image; Reconstructing the preprocessed image through a pre-established deep learning reconstructionmodel to obtain a high-resolution blood vessel wall imaging image; and identifying the plaque in the high-resolution vascular wall imaging image through a pre-established deep learning plaque identification model. Through the scheme, the technical problem that the plaque condition cannot be simply and efficiently determined in the prior art is solved, and the technical effects of simply and efficiently converting an under-sampled image into a high-resolution image and accurately identifying the plaque condition from the high-resolution image are achieved.
Description
technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a magnetic resonance imaging and plaque identification method and device. Background technique [0002] Magnetic resonance imaging is a relatively advanced modern medical imaging technology, which is of great significance in scientific research and clinical diagnosis. However, the slow speed of MRI has seriously hindered the development of MRI technology. Magnetic resonance vessel wall imaging is a non-invasive imaging method that can detect head and neck integrated arterial vessel walls and plaques, and its imaging speed and quality will affect the identification of head and neck plaques. [0003] Currently proposed magnetic resonance imaging techniques generally only realize head and neck integrated vessel wall imaging from the perspective of adjusting the physical method of imaging. Plaque identification in imaging becomes more difficult. [0...
