Artifacts, normal variants, and imaging pitfalls of musculoskeletal magnetic resonance imaging

Area of Science:

• Radiology
• Medical Imaging
• Orthopedics

Background:

• Musculoskeletal Magnetic Resonance Imaging (MRI) is a crucial diagnostic tool.
• Accurate interpretation of MRI requires distinguishing between pathology and non-pathological findings.
• Artifacts, normal variants, and imaging pitfalls can mimic pathology, leading to misdiagnosis.

Purpose of the Study:

• To catalogue common artifacts, normal variants, and imaging pitfalls encountered in musculoskeletal MRI.
• To provide a reference for radiologists and clinicians to improve diagnostic accuracy.
• To reduce the incidence of misdiagnosis in musculoskeletal MRI.

Main Methods:

• Review of a diverse range of musculoskeletal MRI cases.
• Identification and categorization of common imaging artifacts.
• Documentation of normal anatomical variants that may be mistaken for pathology.
• Analysis of common imaging pitfalls leading to misinterpretation.

Main Results:

• A comprehensive list of frequently observed artifacts in musculoskeletal MRI.
• Detailed descriptions of normal variants that can pose diagnostic challenges.
• Examples of common imaging pitfalls and their potential impact on diagnosis.
• Illustrations and explanations to aid in the recognition of these phenomena.

Conclusions:

• Cataloguing artifacts, variants, and pitfalls is essential for accurate musculoskeletal MRI interpretation.
• Awareness of these phenomena can significantly improve diagnostic confidence.
• This resource aims to enhance the quality of musculoskeletal MRI diagnosis and patient care.
