While Deep Learning (DL) architectures, such as U-Net and its extensions are very effective in medical image segmentation tasks, they often struggle with preserving fine-grained details and global contextual information. This is especially challenging for MRI data segmentation, where anatomical structures are characterized by irregular boundaries and variations in shape, contrast, and scale. To address this challenge, we propose a novel DL architecture for MRI segmentation across different anatomical structures. Specifically, the architecture introduces a module, named Multi-Resolution Feature Fusion (MRFF), that can be easily integrated into any U-Net-like architecture. The MRFF is integrated in all levels of an encode-decoder structure, along with attention mechanisms and skip connections to extract features at multiple resolutions, enabling the model to capture both fine-grained details and global contextual information. We evaluate the MRFFU-Net on two publicly available benchmark MRI datasets of different anatomical targets; one for Cerebrospinal Fluid (CSF) segmentation in spinal MR scans, and one for left atrium cardiac segmentation, from the Medical Segmentation Decathlon (MSD) challenge. Experimental results indicate that MRFFU-Net outperforms state-of-the-art models across multiple evaluation metrics, demonstrating its effectiveness in MRI segmentation.", "url": "https://wpnews.pro/news/multi-resolution-feature-fusion-u-net-for-magnetic-resonance-imaging", "canonical_source": "https://arxiv.org/abs/2610.00279", "published_at": "2026-10-02 04:00:00+00:00", "updated_at": "2026-10-02 04:17:46.453777+00:00", "lang": "en", "topics": ["machine-learning", "computer-vision", "ai-research", "artificial-intelligence"], "entities": ["MRFFU-Net", "Multi-Resolution Feature Fusion", "U-Net", "Medical Segmentation Decathlon", "arXiv"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/multi-resolution-feature-fusion-u-net-for-magnetic-resonance-imaging", "markdown": "https://wpnews.pro/news/multi-resolution-feature-fusion-u-net-for-magnetic-resonance-imaging.md", "text": "https://wpnews.pro/news/multi-resolution-feature-fusion-u-net-for-magnetic-resonance-imaging.txt", "jsonld": "https://wpnews.pro/news/multi-resolution-feature-fusion-u-net-for-magnetic-resonance-imaging.jsonld"}}
