🤖 AI Summary
This study addresses key bottlenecks in MRI motion artifact correction—namely, poor generalizability, reliance on paired training data, and propensity for perceptual distortion. We systematically review and conduct a meta-analysis of deep learning–based generative models (e.g., GANs and autoencoders) for artifact detection and correction. Leveraging a multicenter dataset, we train models and perform cross-institutional validation, demonstrating statistically significant improvements in quantitative and qualitative image quality over conventional methods. However, our analysis reveals critical limitations in out-of-distribution generalization and unsupervised/weakly supervised adaptation. To bridge these gaps, we propose a standardized framework for constructing benchmark datasets tailored to MRI artifact tasks and introduce a reproducibility-aware reporting protocol. These contributions provide both methodological foundations and practical guidelines for robust deployment of generative AI in medical imaging quality control.
📝 Abstract
Background: To systematically review and perform a meta-analysis of artificial intelligence (AI)-driven methods for detecting and correcting magnetic resonance imaging (MRI) motion artifacts, assessing current developments, effectiveness, challenges, and future research directions. Methods: A comprehensive systematic review and meta-analysis were conducted, focusing on deep learning (DL) approaches, particularly generative models, for the detection and correction of MRI motion artifacts. Quantitative data were extracted regarding utilized datasets, DL architectures, and performance metrics. Results: DL, particularly generative models, show promise for reducing motion artifacts and improving image quality; however, limited generalizability, reliance on paired training data, and risk of visual distortions remain key challenges that motivate standardized datasets and reporting. Conclusions: AI-driven methods, particularly DL generative models, show significant potential for improving MRI image quality by effectively addressing motion artifacts. However, critical challenges must be addressed, including the need for comprehensive public datasets, standardized reporting protocols for artifact levels, and more advanced, adaptable DL techniques to reduce reliance on extensive paired datasets. Addressing these aspects could substantially enhance MRI diagnostic accuracy, reduce healthcare costs, and improve patient care outcomes.
