Visual Inspection of pulsatile motion artefacts in single volunteers. Visual inspection of pulsatile motion artefacts (24^th diffusion encoding gradient, smallest deviation from the z-axis) shows exemplary obvious artefacts (white arrow) in the superior cerebellum and the mesencephalon in non-gated data of two volunteers (a: left upper row, b: left upper row) in contrast to cardiac-gated data (a: left bottom row, b: left bottom row), almost disappeared after image averaging (a: right column, b: right column). In case of the 17^th diffusion encoding gradient (largest deviation from the z-axis) obvious artefacts are seen in the mesencephalon in non-gated data (c: left upper row), not visible in the cardiac-gated data (c: left bottom row) and after averaging (c: right column).
