This work is to analyze the
respiratory waveforms from dynamic liver MR images related to the motion
artifacts in arterial phase images induced by the contrast-media
administration. The discriminative metrics were defined to quantify the likelihood
of the acutely and temporally impaired breath-holding by the subjects who
received gadoxetate disodium and gadobenate dimeglumine contrast agents. Our preliminary
results show that the indicative metrics derived from recorded respiratory
waveforms objectively confirm prior reported observations that gadoxetate
disodium has a significantly higher likelihood of inducing acute transient
breath-holding difficulties that adversely affect arterial phase image quality.
