Usually, a cross-sectional 2D cine stack is acquired perpendicular to the vessel's axis. However, this method requires a considerable patient collaboration and precise planning of image planes. The present study compares a recently introduced 3D self-navigated free-breathing high-resolution whole heart CMR sequence (3D self nav) allowing a multiplanar retrospective reconstruction of the aortic root as an alternative to the 2D cine technique for determination of aortic root diameters.<h4>Methods</h4>A total of 6 cusp-commissure (CuCo) and cusp-cusp (CuCu) enddiastolic diameters were measured by two observers on 2D cine and 3D selJournal of cardiovascular magnetic resonance : official journal of the Society for Cardiovascular Magnetic Resonance65https://www.ebi.ac.uk/biostudies/studies/S-EPMC8157643biostudies-literature2D cine vs. 3D self-navigated free-breathing high-resolution whole heart cardiovascular magnetic resonance for aortic root measurements in congenital heart disease.PMC8157643Bouchardy JBlanche CNussbaumer CPavon AGMonney PStuber MSchwitter JRutz TPiccini Dfalse2D cine vs. 3D self-navigated free-breathing high-resolution whole heart cardiovascular magnetic resonance for aortic root measurements in congenital heart disease.<h4>Background</h4>Cardiovascular magnetic resonance (CMR) is considered the method of choice for evaluation of aortic root dilatation in congenital heart disease.
