Abstract:
Many MR artifacts are not understandable in terms of previous imaging experience. A variety of artifacts is presented here; their origins and elimination are discussed.
Insights
This study explains common Magnetic Resonance (MR) artifacts that are difficult to understand from prior imaging experience. It details artifact origins and methods for their elimination.
Area of Science:
- Medical Imaging
- Radiology
- Physics
Background:
- Magnetic Resonance (MR) imaging is a powerful diagnostic tool.
- Understanding and mitigating artifacts is crucial for accurate image interpretation.
- Many MR artifacts lack intuitive explanations based on general imaging experience.
Purpose of the Study:
- To present a variety of common MR artifacts.
- To elucidate the underlying physical principles and origins of these artifacts.
- To discuss practical strategies for artifact elimination and reduction.
Main Methods:
- Review and categorization of prevalent MR artifacts.
- Explanation of artifact generation mechanisms.
- Description of image correction and avoidance techniques.
Main Results:
- Detailed presentation of diverse MR artifacts.
- Clear explanations of artifact sources, often counterintuitive.
- Effective methods for artifact suppression and correction are provided.
Conclusions:
- A comprehensive understanding of MR artifact origins is essential for radiologists and technologists.
- Implementing discussed elimination strategies can improve diagnostic image quality.
- This work aims to enhance the interpretability of MR images by addressing common artifact challenges.
