T2 relaxation time mapping in MRI is regarded as a promising non-invasive biomarker for the individual risk of osteoarthritis and early osteoarthritis diagnosis. To evaluate validity of T2 mapping, this study analyzed T2 values in 101 subjects with and 41 subjects without risk factors for knee osteoarthritis in four knee cartilage compartments (medial and lateral femur; med. and lat. tibia). After adjustment for age, gender, BMI, KL score and group membership, results showed that subjects with risk factors had significantly higher T2 values. Also, there was a significant correlation between T2 values and focal knee lesions. T2 values increased over 24 months in all groups, however, differences in T2 increase between the groups were not significant.
