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.

DTI of human skeletal muscle: the effects of diffusion encoding parameters, signal‐to‐noise ratio and T2 on tensor indices and fiber tracts
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. Expand
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. Expand
Techniques and applications of skeletal muscle diffusion tensor imaging: A review
An overview of DTI studies covering the technical, demographic, and clinical aspects ofDTI in skeletal muscles is provided and the reported normal variance in skeletal muscle diffusion parameters is covered. Expand
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.
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. Expand
Diffusion Tensor MRI of the Heart – In Vivo Imaging of Myocardial Fiber Architecture
The basics of diffusion imaging are discussed, as well as various reconstruction and analysis models, which have great potential to better understand cardiac function, characterize cardiac pathology, and understand myofiber remodeling in response to injury or disease. Expand
Evaluation of skeletal muscle DTI in patients with duchenne muscular dystrophy
It is suggested that measuring mean water T2, %fat and SNR is essential to ascribe changes in DTI measures to intrinsic diffusion changes or to confounding influences. Expand
The importance of correcting for signal drift in diffusion MRI
To investigate previously unreported effects of signal drift as a result of temporal scanner instability on diffusion MRI data analysis and to propose a method to correct this signal drift.
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. Expand
