Fig 2. Arterial phase SNR in the aorta (left) and in the portal vein (right), comparison of different contrast agent application protocols (#1–4).

Fig 2

SNR in the aorta and portal vein were significantly higher in protocol groups using the slower injection rate of 1 ml/sec, as compared to an injection rate of 2 ml/sec (p<0.0001 and p = 0.0016). * indicates a statistical significance.
