S1) Baseline characteristics and performed diagnostic procedures considered for the reference standard; S2) Cross tables for sensitivity calculations of intracardiac structures; S3) Cross tables for sensitivity calculations of great extracardiac vessels; S4) Cross tables for sensitivity calculations of small extracardiac vessels; S5) Examples for the CMR image quality evaluation (Likert 1 to 5). S6) Estimates of regression coefficients with 95% confidence intervals and p-values of mixed models to compare contrast and slopes between the three MRI sequences; S7) Exemplary semi-automatic assessment of the signal intensity curves of the vessel wall and the lumen of the ascending aorta; S8) Estimated marginal means of the quantitative vessel assessment with two-sided 95% confidence intervals regarding A) contrast and B) vessel sharpness (slopes); S9) Vessel diameter measurement agreement between the two readers.
