Investigation of resolution effects using a specialized diffusion tensor phantom

Abstract

Purpose: The clinical potential of the diffusion imaging‐based analysis of fine brain structures such as fornix or cingulum is high due to the central role of these structures in psychiatric diseases. However, the quantification of diffusion parameters in fine structures is especially prone to partial volume effects (PVEs). Methods: In this study, a phantom for the investigation of PVEs and their influence on diffusion parameters in fine structures of different diameter is presented. The phantom is produced by winding wet polyester fibers onto a spindle. The resulting fiber strands have well defined square cross‐sections of 1–25 mm 2 and provide a homogeneous and high fractional anisotropy (FA ≈ 0.9). Results: Several PVEs are demonstrated and analyzed. It is shown that inferred results such as the fiber geometry and diffusion parameters strongly depend on the relative position of the structure of interest to the voxel‐grid. Several implications of PVEs on post‐processing methods such as Tract‐based Spatial Statistics and fiber tractography are demonstrated. Conclusion: These results show that the handling of PVEs in common post‐processing tasks can be problematic, and that the presented phantom provides a valuable tool for the improvement and evaluation of these effects.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ex vivo imaging and tracing or physically and numerically simulated phantoms allow validation to some extent, and in specific circumstances such as basic fiber configurations.

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.
