irregular breahing during 3DFT T2w-TSE liver imaging cause motion artifact due to long echo-train length even with PACE technique. If we assume irregularity changes respiration period excluding cohghing and sighing, we can correct superior-infirior directional motion using navigator information before and after triggering. Navigator after triggering shows large variation.
