Fig. 1From: Radial self-navigated native magnetic resonance angiography in comparison to navigator-gated contrast-enhanced MRA of the entire thoracic aorta in an aortic patient collectiveStudy flow chart. A Overall image quality was tested for statistical significance in 31 native-self-navigated (SN)-MRA and 61 contrast enhanced (CE)-MRA with binary and 4-point scale ratings (orange). B Analysis of the influence of artifacts on both sequences (blue). C Subgroup analysis of patients following aortic surgery only (green). D In the intraindividual comparison of 10 patients with both types of MRA the overall image quality was tested (red).
