Figure 6a.  (a-c) Axial T1-weighted GRE MR images (120/4.2) obtained with breath holding at 0.5 T (a), 1.0 T (b), and 1.5 T (c) show the superior hepatic veins. Note the out-of-phase appearance at 1.0 T (b) and the in-phase appearance at 1.5 T (c). Also note the aortic artifact in the left lobe of the liver on all three images (arrowhead). (d-f) Corresponding graphs show SNR (d), CNR (e), and relative contrast (RC) (f) according to field strength. Kid = kidney.
