  Objective: To evaluate the difference in the age-related cartilage changes of the humeral head with T1ρ relaxation time mapping and assess the normal distribution of the proteoglycan content of the humeral head in healthy volunteers without any symptoms or structural disorders. Materials and Methods: Twenty male volunteers (10 young subjects, 10 elderly subjects) for each generation group (mean age, young subjects: 30.2 ± 2.3 years; elderly subjects: 62.6 ± 6.2 years) participated in this study. Spectral attenuated inversion recovery T2-weighted imaging and T1ρ relaxation time mapping were performed using 3.0-Tesla magnetic resonance imaging. Regions of interest were located on the humeral cartilage on oblique coronal images from the bone–tendon junction to the inferior articular surface and divided the surface of the.. View More»
