Pulmonary MRI is well-known to be susceptible to artifacts resulting from cardiac and respiratory motion or flow. In addition however, truncation artifacts or Gibbs ringing introduced at the boundaries between lung and surrounding body tissue are present, especially when imaging with low spatial resolution. In this work, the effects of these Gibbs artifacts on the reconstructed images as well as on quantitative lung parameters like T1 or pulmonary perfusion are demonstrated.
