Unveiling Zipper Artifact: Causes, Impacts, And Mitigation Strategies For High-Quality Mri Imaging
Zipper artifact is a common MRI artifact caused by susceptibility gradients at tissue-air interfaces. It creates linear, bright-dark bands or streaks on MRI images, reducing image quality and potentially obscuring diagnostic information. Intra-voxel zipper artifact arises within a single voxel, phase zipper lines occur due to phase inconsistencies, and parallel zipper lines form at tissue-air boundaries. To prevent zipper artifact, anti-aliasing techniques, optimizing gradient strength, and parallel imaging are employed.
