The challenge of mapping the human connectome based on diffusion tractography
The encouraging finding that most state-of-the-art algorithms produce tractograms containing 90% of the ground truth bundles (to at least some extent) is reported, however, the same tractograms contain many more invalid than valid bundles, and half of these invalid bundles occur systematically across research groups.

It is concluded that accurate DTI of skeletal muscle requires an SNR of at least 25, a b value of between 400 and 500 s/mm2, and data acquired with at least 12 diffusion gradient directions homogeneously distributed on half a sphere.

The consensus-based technical recommendations for renal DWI aim to facilitate inter-site harmonization and increase clinical impact of the technique on a larger scale by setting a framework for acquisition protocols for future renalDWI studies.
Skeletal muscle diffusion tensor‐MRI fiber tracking: rationale, data acquisition and analysis methods, applications and future directions
The use of diffusion tensor (DT)‐MRI muscle fiber tracking for the study of muscle architecture is described and examples are presented of how DT‐MRI fiber tracking has been used to provide new insights into how muscles function.

Diffusion‐tensor MRI reveals the complex muscle architecture of the human forearm
To design a time‐efficient patient‐friendly clinical diffusion tensor MRI protocol and postprocessing tool to study the complex muscle architecture of the human forearm.
Feasibility of diffusion tensor imaging (DTI) with fibre tractography of the normal female pelvic floor
The feasibility of visualising the complex three-dimensional pelvic floor architecture using 3T-DTI with fibre tractography is demonstrated and DTI of the deep female pelvic floor may provide new insights into pelvic floor disorders.
Reproducibility of diffusion tensor imaging in human forearm muscles at 3.0 T in a clinical setting
The reproducibility of six diffusion tensor imaging parameters, i.e., the tensor eigenvalues, mean diffusivity, fractional anisotropy, and ellipsoid eccentricity, was demonstrated using a 7 min 40 sec scan protocol.
