UNASSIGNED: Purpose: @entity1 with @entity1614 require repeated imaging for monitoring of aortic root @entity439 . Therefore, we evaluated the agreement and reproducibility of cine-MRI and echocardiography measurements of the sinuses of Valsalva in @entity1 with suspected @entity1614 . Materials and Methods: 51 consecutive @entity1 with suspected @entity1614 were prospectively examined using cine-MRI and echocardiography. Two readers independently measured aortic root diameters at the level of the sinuses of Valsalva in both cine-MRI and echocardiography. Statistics included intraclass correlation coefficient, Pearson correlation coefficient, Bland-Altman analysis, and two-sided t-test. Results: In 38 of the 51 individuals (74.5%), the diagnosis of @entity1614 was established according to the criteria of the Ghent-2 nosology. Cine-MRI measurements of the sinuses of Valsalva revealed a strong correlation with echocardiography (r=0.929), but a statistically significant bias of -1.0mm (p<0.001). The mean absolute diameter for sinuses of Valsalva obtained by cine-MRI was 32.3  5.8mm as compared to 33.4  5.4mm obtained by echocardiography. Interobserver agreement of measurements of the sinuses of Valsalva was higher for cine-MRI than for echocardiography (p=0.029). Conclusion: Despite small, but statistically significant differences in terms of agreement and reproducibility, cine-MRI and echocardiographic measurements of aortic root diameters provide comparable results without a significant clinical difference. Therefore both techniques may be used for monitoring of the aortic root in @entity1 with @entity1614 . Key points:       Cine-MRI (ICC: 0.93, CI: 0.88-0.96) and echocardiography (ICC: 0.90, CI: 0.82-0.94) allow assessment of aortic root diameters in @entity1 with @entity1614      Cine-MRI offers higher reproducibility of aortic root diameters than echocardiography (95% limits of agreement of   3.6mm versus   5.0mm, p=0.029)      Aortic root measurements with cine-MRI and echocardiography reveal a small (mean difference; -1.0mm) but statistically significant offset (p=0.0004) Citation Format:       Bannas P., Rybczynski M., Sheikhzadeh S. etal.
