The purpose of this study was to measure T1rho and T2
relaxation times in vivo in healthy controls, subjects
with mild OA, and subjects with femoroacetabular
impingement (FAI). The volunteers were scanned with a
segmented 3D SPGR MAPSS T1rho/T2 sequence on one hip and
the cartilage was clinically scored for lesions. The
femoral and acetabular cartilage were segmented
separately and then segmented into 8 equal regions.
Significant increases in the T1rho and T2 relaxation
times were seen in the acetabular cartilage while no
significant changes were seen in the femoral cartilage.
