T1rho Fractional-order Relaxation of Human Articular Cartilage
T1rho Fractional-order Relaxation of Human Articular Cartilage
T1rho imaging is a promising non-invasive diagnostic tool for early detection of articular cartilage degeneration. A mono-exponential model is normally used to describe the T1rho relaxation process. However, mono-exponentials may not adequately to describe NMR relaxation in complex, heterogeneous, and anisotropic materials, such as articular cartilage. Fractional-order models have been …
