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.
