Whilst dark-rim artefacts have been studied in 2D first-pass perfusion, they could also have the potential to be produced in the through-plane direction of 3D first-pass perfusion due to the typically coarse resolution employed in the second phase-encoding direction. An examination of the potential for this Gibbs truncation effect, and its relationship to the also troubling partial-volume effect, is studied in conical and anatomical numerical phantoms as well as a representative in-vivo dataset.
