Implication

Ex-vivo study reveals that quantitative MRI T2 texture features correlate with histological cartilage degeneration in donor knees, indicating potential for noninvasive cartilage assessment.

Key Points

To evaluate the relationship between quantitative MRI T2 textural features and histological markers of articular cartilage degeneration.
Ten fresh non-frozen donor knees were scanned at 3T and 7T using 3D-DESS and 3D-TESS sequences, with automatic segmentation and co-registration to T2 maps.
Nine osteochondral plugs per knee were harvested from the distal femur for Mankin scoring and polarized light microscopy to quantify collagen orientation and parallelism.
Relationships between MRI T2 texture features and histological scores were analyzed using partial Spearman's correlation coefficients and mixed models.
Mean T2 and six textural features (autocorrelation, contrast, correlation, entropy, sum entropy, and inverse difference moment normalized) significantly correlated with the Mankin score.
Autocorrelation, contrast, and entropy significantly correlated with collagen orientation, while no texture features correlated with collagen parallelism.
Statistical modeling showed no significant effect of magnetic field strength (3T vs 7T) or pulse sequence (3D-DESS vs 3D-TESS) on predicting Mankin scores.
