Correlation time (τc) is novel MRI parameter that can be calculated from time demanding dispersion measurements of longitudinal relaxation times in the rotating frame (T1ρ). Therefore methods able to accelerate data acquisition are needed for τc mapping of cartilage in vivo. Present results demonstrate that partial k-space acquisition and Parallel Imaging can reduce imaging time while having small influence on τc values. Although long TurboGRE readout train significantly decreases τc values, it allows the τc mapping of cartilage in clinically acceptable measurement times. The τc mapping may therefore serve for the noninvasive in vivo evaluation of cartilage at 3T.
