CE-MRA combines a fast T1-weighted gradient-echo acquisition with an intravenously administered paramagnetic contrast agent. Higher relaxivity gadolinium-chelate extracellular contrast agents can provide improved vascular signal-to-noise and contrast-to-noise ratios for an equimolar dose of a lower relaxivity gadolinium-chelate extracellular contrast agent. 6.7 ml of Gadobutrol (Gadovist) were used in this study.
