Early detection of articular cartilage damage is critical to the success of joint preserving surgeries for patients with femoroacetabular impingement (FAI). Delayed Gadolinium-Enhanced MRI of Cartilage (dGEMRIC) and T2 mapping can detect early biochemical changes in cartilage. We investigated the relationship of dGEMRIC and T2 with morphologic cartilage assessment at 3T. dGEMRIC was very sensitive to cartilage damage (71% and 86% for minor and severe lesions, respectively), whereas T2 was very specific (87% for any type of lesion). This preliminary study suggests that the combination of morphologic MRI, dGEMRIC and T2 could be effective in detecting and staging cartilage damage.
