In this study we utilize a deep learning approach to automatically segment the femoral and acetabular cartilages in the hip. From these segmentations we also calculate T1ρ and T2 relaxation times then compare to manual segmentations and their T1ρ and T2 values. We show the T1ρ and T2 relaxation times, calculated using manual and automatic segmentations, are very correlated, R values above .94, and comparable.
