Summary
Radiomic features from MRI correlate with shoulder movement in patients with rotator cuff tears, especially when grouped by clinical scores. This links static imaging to dynamic function for better shoulder assessment.
Area of Science:
- Orthopedics
- Radiology
- Biomedical Engineering
Background:
- Rotator cuff tears (RCTs) cause significant shoulder dysfunction.
- Magnetic resonance imaging (MRI) provides static tendon integrity but doesn't fully explain functional loss.
- Optoelectronic motion capture offers quantitative 3D shoulder kinematics.
Purpose of the Study:
- Investigate the relationship between preoperative MRI radiomic features and shoulder kinematic parameters in patients with supraspinatus tendon tears.
- Determine if clinical scores influence radiomic-kinematic associations.
Main Methods:
- 73 RCT patients underwent preoperative MRI and 3D shoulder kinematic assessment.
- Radiomic features extracted from MRI; kinematic parameters computed from motion capture.
- Correlation analyses performed on the full cohort and ASES score subgroups.
Main Results:
- No significant associations found in the overall cohort.
- Moderate radiomic-kinematic correlations emerged in ASES subgroups.
- Positive and negative correlations identified, mainly involving texture and intensity features.
Conclusions:
- Integrating radiomics with dynamic motion analysis links MRI-derived tissue alterations to functional shoulder performance.
- Combining imaging biomarkers with functional assessments enhances shoulder pathology evaluation.
