Truncation artifacts

Truncation artifacts (also known as Gibbs, ringing, or spectral leakage artifacts) typically appear as multiple fine parallel lines immediately adjacent to high-contrast interfaces due to truncation (shortening) of Fourier series approximation. These artifacts are particularly problematic in spinal imaging, in which they may artifactually widen or narrow the cord or mimic a syrinx.
