Abstract

Objectives

To investigate the superiority of radial volumetric breath-hold examination (r-VIBE) with k-space weighted image contrast reconstruction (KWIC) over Cartesian VIBE (c-VIBE) for reducing motion artefacts.

Methods

We acquired r-VIBE-KWIC and c-VIBE images in 10 healthy volunteers. Each acquisition lasted 24 seconds. The volunteers held their breath for decreasing lengths of time during the acquisitions, from 24 to 0 seconds (protocols A–E). Magnetic resonance images at the level of the right portal vein and confluence of hepatic veins were assessed by two readers using a five-point scale with a higher number indicating a better study.

Results

The mean scores for the complete r-VIBE-KWIC series (r-VIBE_full) and first r-VIBE-KWIC series (r-VIBE₁) were not significantly lower than those for c-VIBE in any protocols. The mean scores for c-VIBE were lower than those for r-VIBE_full and r-VIBE₁ in protocols C and D. The mean score for c-VIBE was lower than that for r-VIBE_full in protocol E. The mean score for the eighth r-VIBE-KWIC series (r-VIBE₈) was lower than that for c-VIBE only in protocol B.

Conclusion

r-VIBE-KWIC minimised artefacts relative to c-VIBE at any slice location. The r-VIBE-KWIC’s sub-frame images during the breath-holding period were hardly affected by another failed breath-holding period.

Key Points

• A two-reader study revealed r-VIBE-KWIC’s advantages over c-VIBE

• The image quality of r-VIBE-KWIC’s sub-frame images was maintained during breath holding

• Full-frame r-VIBE-KWIC images minimized motion artefacts caused by breathing

• A complete breath holding over half the acquisition time is recommended for c-VIBE

• c-VIBE was susceptible to respiratory motion especially in the subphrenic region
