Scan time, SNR and aortic diameter. The scan time was significantly shorter on native-SN-MRA than on conventional high-resolution CE-MRA (p < 0.01). SNR values were significantly higher on CE-MRA (p < 0.02). In the intraindividual comparison of patients with both types of MRA, the measurement of the pathologic and normal diameters did not show a significant difference (p < 0.899).
