Synopsis

Keywords: Tendon/Ligament, Osteoarthritis

This study was performed to investigate gender-related and age-related differences in ultra-short echo-time (UTE) T parameters in the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and patellar tendon (PT). A pointwise encoding time reduction with radial acquisition (PETRA) sequence was used to measure single-component and multi-component PETRA-T parameters in the ACL, PCL, and PT at 3.0T in 18 healthy volunteers. There were significant correlations between age and single-component and multi-component PETRA-T1p parameters in the ACL and PCL but not the PT. There were no significant differences in PETRA-T parameters in the ACL, PCL, or PT between males and females.
