To employ a long-T1 species suppression module consisting of a non-selective IR pre-pulse followed by a time delay to eliminate the ghosting artifacts in segmented ECG-gated IR-prepared sequences caused by the signal oscillations of body fluids with long T1 values.
In phantom and in-vivo experiments playing a suppression module consisting of a non-selective inversion pulse and a pre-delay of 2200 ms to 2600 ms eliminates long-T1 species ghosting in segmented ECG-gated IR-prepared sequences without affecting the SNR of the myocardium. As artifacts due to multiple long-T1 species are suppressed using the same pre-delay the ghosting can be eliminated without scanner operator involvement.
