Comparative Study
The compositional difference between ankle and knee cartilage demonstrated by T2 mapping at 7 Tesla MR.
The aim was to systematically compare T2 relaxation times of the knee and ankle cartilage within subjects at 7T. ⋯ This is the first study to systematically compare within-subject T2 values in the knee and ankle non-invasively, in vivo. Our results are in agreement with the previous findings demonstrating different biochemical and biomechanical properties between the knee and ankle cartilage.
