Fig. 2From: Aortic length measurements for pulse wave velocity calculation: manual 2D vs automated 3D centreline extractionExamples of images used. For 2D centreline analysis: (a) oblique-sagittal slice of a 2D cine, and (b) oblique-sagittal GRE image with transverse saturation slabs indicating the positions of the PC-CMR images. For 3D centreline analysis: oblique-sagittal reformat from volumetric (c) DIR-TSE Black-Blood, (d) bSSFP and (e) contrast-enhanced MRABack to article page
