UTE T2* sequences can be used to assess the temporomandibular joint disc in vivo with differences in T2* values in symptomatic patients compared to asymptomatic volunteers. This study proves feasibility of in vivo quantitative MR evaluation of TMJ disc using the UTE T2* technique, which may provide sensitive and objective measure of TMJ disc degeneration in TMD patients.
