Knobel, 2011 [100] | 1.5 T, contrast enhanced CMRA, diameters measured on images perpendicular to the vessel | 41:28 | 2–20 |
Kutty, 2012 [93] | 1.5 T; magnitude image of a through-plane free-breathing phase contrast sequence; cross sectional area calculated based on measurements of the maximal external aortic diameter perpendicular to the vessel and perpendicular to the maximal diameter obtained midway between the level of the pulmonary valve and the bifurcation of the branch pulmonary arteries | 55:50 | 4–20 |
