FS – fat-suppressed, MRA – MR angiography, NA – not applicable, NSA – number of signals acquired, TE – echo time, T1W – T1-weighted, TR – repetition time

Administration of gadolinium contrast agent – dose of 0.1 ml/kg of bodyweight, injection rate 4-4.5 ml/s

^*Postcontrast images are obtained with the same sequence;

^¥Inversion time 150 ms;

^†Inversion time 220 ms ;

^‡These data refer to breath-hold acquisitions in the abdomen;

^§For anatomic regions where breath-hold acquisition is not necessary we routinely increase the resolution.
