Figure 12. Aortic Imaging Techniques to Determine the
Presence and Progression of Aortic Disease
A, Schematic shows the leading-edge to leading-edge measurement technique used in
echocardiography, from le to right: measurement of the aortic root (sinuses of Valsalva),
sinotubular junction, and proximal tubular ascending aorta.
B, Inner-wall to inner-wall measurements of the aortic root used in MRI and CT. In addition,
a consistent approach to measuring all 3 sinuses with MRI and CT is necessary. e sinus-to-
commissure and sinus-to-sinus measurements can both be used, but consistency is necessary for
interval surveillance.
C, Standard measurement locations for MRI and CT with the inner-wall to inner-wall
technique.
