To provide MRI-based T2-relaxation time reference data for layer- and subregion-specific cartilage composition in an adult cohort without MRI-based evidence of pathological cartilage changes.
Key Findings:
T2-relaxation times vary significantly between superficial and deep cartilage layers, highlighting the need for layer-specific assessments in OA detection.
Age, sex, and cartilage morphology influence T2-relaxation measurements, indicating the importance of these factors in clinical evaluations.
Reference T2-values established for healthy knee cartilage can aid in early OA detection, potentially improving patient outcomes.
Interpretation:
Layer-specific T2-relaxation measurements can serve as a non-invasive biomarker for early detection of osteoarthritis, providing insights into cartilage health and degeneration, which may guide clinical decision-making.
Limitations:
Study limited to a specific population cohort, which may affect generalizability to broader populations.
Potential biases in MRI interpretation due to subjective analysis, which could influence the reliability of findings.
Conclusion:
Establishing reference T2-values enhances understanding of OA pathophysiology and may improve early detection and monitoring of knee cartilage health.
