The purpose of this study was to evaluate articular
cartilage degeneration in healthy subjects and patients with knee joint-pain as
the only clinical manifestation using T1ρ measurements and to examine the
interrelationship between cartilage abnormalities. Quantitative assessment of
cartilage was performed using T1ρ mapping technique in 5 healthy volunteers and
17 knee joint-pain patients. T1ρ values were significantly elevated among
patients with knee joint-pain compared to normal controls. Proteoglycan reduced
in patients with knee joint-pain as the only clinical manifestation. Comparing
to routine MR, T1ρ mapping could be more useful for these patients
