Figure 1. Higher SNR and CNR in time resolved MR-Angiography does not translate into improved image quality.

Figure 1

Gadobutrol was utilized as the contrast agent in a 80 year old female with SNR/CNR values of 93/65 for the anterior tibial artery, 125/101 for the posterior tibial artery and 90/62 for the peroneal artery. Gadoterate meglumine administered in a 61 year old female resulted in SNR/CNR values of 60/21 for the anterior tibial artery, 55/21 for the posterior tibial artery and 52/19 for the peroneal artery. Image quality was rated good to excellent by both readers in both cases.
