Microstructure informed tractography: pitfalls and open challenges
Open accessAbstract
One of the major limitations of diffusion MRI tractography is that the fiber tracts recovered by existing algorithms are not truly quantitative. Local techniques for estimating more quantitative features of the tissue microstructure exist, but their combination with tractography has always been considered intractable. Recent advances in local and global modeling made it possible to fill this gap and a number of promising techniques for microstructure informed tractography have been suggested, opening new and exciting perspectives for the quantification of brain connectivity. The ease-of-use of the proposed solutions made it very attractive for researchers to include such advanced methods in their analyses; however, this apparent simplicity should not hide some critical open questions raised by the complexity of these very high-dimensional problems, otherwise some fundamental issues may be pushed into the background. The aim of this article is to raise awareness in the diffusion MRI community, notably researchers working on brain connectivity, about some potential pitfalls and modeling choices that make the interpretation of the outcomes from these novel techniques rather cumbersome. Through a series of experiments on synthetic and real data, we illustrate practical situations where erroneous and severely biased conclusions may be drawn about the connectivity if these pitfalls are overlooked, like the presence of partial/missing/duplicate fibers or the critical importance of the diffusion model adopted. Microstructure informed tractography is a young but very promising technology, and by acknowledging its current limitations as done in this paper, we hope our observations will trigger further research in this direction and new ideas for truly quantitative and biologically meaningful analyses of the connectivity.

Structural connectome analyses are most convincing when integrated with neuroanatomical knowledge, functional data, and careful control of tractography biases.
“Structural connectome analyses are most convincing when integrated with neuroanatomical knowledge, functional data, and careful control of tractography biases (Assaf et al., 2019; Daducci et al., 2016).”

Section 3.2 (Biological plausibility; page unavailable) recommends comparing tractography estimates with known anatomy, while the Introduction and Section 5 warn that overlooked tractography pitfalls can bias connectivity analyses. The passages do not recommend integrating structural analyses with functional data; a search for functional MRI, functional data, and functional connectivity found no supporting passage.

Experimental — accuracy not yet measuredHigher angular-resolution methods, better distortion correction, and anatomically informed tractography improve matters, yet they do not eliminate the inverse problem.
“Higher angular-resolution methods, better distortion correction, and anatomically informed tractography improve matters, yet they do not eliminate the inverse problem (Daducci et al., 2016; Tournier et al., 2011).”

Section 5 (Discussion and conclusion; page unavailable) says anatomical constraints and careful handling of partial fibers matter, but global methods can still overfit and yield anatomically implausible results. Section 4.1 discusses correction of signal-intensity inhomogeneity, not distortion correction. The paper does not establish that higher angular resolution or better distortion correction improves tractography while leaving the inverse problem unresolved. (LLM, conf=0.85)

Tractography visualizes a model of anatomical connectivity constrained by diffusion data, not anatomy itself.
“Tractography, therefore, visualizes a model of anatomical connectivity constrained by diffusion data, not anatomy itself (Daducci et al., 2016; Tournier et al., 2011).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
