Table 1 SNR, CNR and scan duration for nonenhanced and 2D-SENSE CE-MRA.

From: 2D-SENSE in isotropic slow infusion contrast-enhanced whole-heart coronary magnetic resonance angiography at 3 T

Parameter Non enhanced whole-heart MRA (T2prep) Whole-heart CE-MRA (Gd-BOPTA, 2D-SENSE)
SNR (blood) 37.5 ± 14.7 121.3 ± 44.0*
CNR (blood-myocardium) 14.4 ± 6.9 101.5 ± 40.8*
Scan duration (min) 9.7 ± 3.6 12.3 ± 7.7
Navigator efficiency (%) 52.3 ± 13.0 47.9 ± 10.7
  1. *Sigificance: p < 0.05 vs. T2prep values (paired two-sided Student t-test)
