In this study, we investigated whether the T1ρ profile of the hip cartilage changes over time in a subject group with asymptomatic cam-type femoroacetabular impingement (FAI). After the initial T1ρ data acquisitions, the scans were repeated on the same group in a mean time interval of 3.3 years. For the majority of the subject group there were no significant T1ρ changes in the whole joint and in different hip cartilage regions. However, 1 patient (out of 12) showed significant (>20%) increased T1ρ values (i.e. proteoglycan reduction).
