This work demonstrates that quantitative MRI can detect regional differences in the hip cartilage of female water polo players and synchronized swimmers; this suggests possible regional differences in cartilage matrix composition between these two groups.
Figure 3: The average T2 Relaxation Times for synchronized swimmers (synchro) and water polo players (water polo) across the total hip cartilage and four subregions: superior-posterior (sup-pos), superior-anterior (sup-ant), inferior-posterior (inf-pos), and inferior-anterior (inf-ant). The average T2 relaxation time means are more stable in water polo players and have more variability in the synchronized swimmers.
