Application of diffusion magnetic resonance imaging (dMRI) to map the complex collagen fibril structures of meniscus is still challenging, due to the short T2/T2* values, low fractional anisotropy (FA) values, and relatively low signal-to-noise (SNR). In this study, we imaged the porcine menisci in a preclinical 7 T system with relatively short echo time (TE ~ 11 ms). A 3D diffusion-weighted spin-echo pulse sequence was used for whole meniscus tractography at 125 µm isotropic resolution.
