The analysis of carotid arteries, especially plaques, in multi-sequence MRI data is crucial for assessing the risk of atherosclerosis and ischemic stroke.
A semi-supervised deep learning-based approach is proposed to integrate multi-sequence MRI data for accurate segmentation of carotid artery vessel wall and plaque.
The approach includes a coarse localization model followed by a fine segmentation model, along with fusion strategies and a multi-level multi-sequence U-Net architecture.
The method addresses challenges of limited labeled data and complex carotid artery MRI through consistency enforcement under various input transformations, showcasing promising results.
