Racial differences in biochemical knee cartilage composition between African-American and Caucasian-American women with 3Â T MR-based T2 relaxation time measurements - data from the Osteoarthritis Initiative

Using T2 relaxation time as a biomarker for the cartilage collagen network, our findings suggest racial differences in the biochemical knee cartilage composition between African-American and Caucasian-American women.
