Study on Artifacts in Magnetic Resonance Imaging (I): Review of Technique-Related Artifacts

Key Points

• This review aims to systematically categorize and analyze technique-related artifacts in MRI, focusing on their causes and implications.
• Artifacts categorized as software-related and hardware-related.
• Focus on common artifacts: aliasing, truncation, cross-talk, zipper, and eddy current.
• Analysis included physical mechanisms, typical imaging appearances, sequence dependencies, clinical pitfalls, and correction strategies.
• Each artifact was systematically described, aiding in understanding their impact on diagnostic accuracy.
• Understanding artifacts contributes to improving image quality and reducing unnecessary retests.
• Knowledge of correction strategies enhances diagnostic reliability in clinical settings.
