Validation of thoracic aortic dimensions on ECG-triggered SSFP as alternative to contrast-enhanced MRA

ConclusionsThoracic aortic dimensions measured on SSFP-MRA and non-ECG-triggered CE-MRA were similar. As expected, SSFP-MRA showed better reproducibility close to the aortic root because of lesser motion artefacts, making it a feasible non-contrast imaging alternative.Key Points•SSFP-MRA provides similar dimensions as non-ECG-triggered CE-MRA.•Intra- and inter-observer reproducibilities improve for the sinus of Valsalva and sinotubular junction with SSFP-MRA.•ECG-triggered SSFP-MRA shows better image quality for landmarks close to the aortic root in the absence of cardiac motion.
