Efforts have been focused on early detection of osteoarthritis using MRI. Our study reports T1, T1ρ and T2 values for knee cartilage and menisci in normal subjects using 3T MRI, and evaluates associations with age, gender, and BMI. We found that WB-FC had higher T1 and lower T2 values than LWB-FC, and WB-FC had higher T1 values in females. T1 values of WB-FC and LM were associated with age, and T1ρ values of WB-FC were associated with BMI. Our study presents novel data on T1 mapping, reinforcing the utility of MRI as a potential tool for early detection of osteoarthritis.
