Artifacts and pitfalls in shoulder magnetic resonance imaging

Area of Science:

• Radiology
• Medical Imaging
• Orthopedics

Background:

• Magnetic resonance imaging (MRI) is a primary diagnostic tool for shoulder lesions.
• Potential pitfalls in MRI interpretation can lead to misdiagnosis.
• Radiologists, especially trainees, may encounter challenges with anatomical variations and artifacts.

Purpose of the Study:

• To compile imaging findings that mimic shoulder injuries on MRI.
• To provide a reference to prevent false-positive and false-negative diagnoses.
• To enhance the accuracy of musculoskeletal MRI reporting for shoulder conditions.

Main Methods:

• Review and compilation of imaging findings.
• Analysis of anatomical variations and artifacts in shoulder MRI.
• Literature review on common diagnostic errors in musculoskeletal radiology.

Main Results:

• Identified common imaging findings that can be mistaken for shoulder injuries.
• Detailed description of artifacts and anatomical variants that may cause diagnostic confusion.
• Categorization of potential pitfalls in shoulder MRI interpretation.

Conclusions:

• Accurate interpretation of shoulder MRI requires awareness of potential pitfalls.
• This compilation serves as a valuable resource for radiologists of all experience levels.
• Improved understanding of non-pathological findings enhances diagnostic precision in shoulder imaging.
