MR imaging artifacts. Challenges and solutions
1Mallinckrodt Institute of Radiology, Washington University School of Medicine, St. Louis, Missouri, USA.
Abstract:
A wide variety of artifacts is routinely encountered on MR images. This article reviews the cause, appearance, diagnostic effect, and available remedies for the artifacts that are most frequently observed on MR images and are of greatest clinical significance. Combined with routine preventive maintenance of imaging equipment, consistent quality control, and appropriate selection of imaging parameters, awareness of the manifestations of these artifacts will allow image quality and diagnostic interpretation to be optimized.
Insights

- Identifying and addressing artifacts is crucial for accurate medical diagnoses.
Purpose of the Study:
- To review the causes, appearance, diagnostic effects, and remedies of common and clinically significant MRI artifacts.
- To provide guidance for optimizing image quality and diagnostic interpretation through artifact awareness.
Main Methods:
- Review of common Magnetic Resonance Imaging (MRI) artifacts.
- Analysis of artifact causes, visual presentation, and impact on diagnosis.
- Discussion of artifact mitigation strategies and preventive measures.
Main Results:
- Common MRI artifacts have identifiable causes and characteristic appearances.
- Awareness of artifact manifestations aids in their recognition and management.
- Effective artifact management improves diagnostic confidence and reduces misinterpretations.
