Contrast-enhanced CT aortic measurements correlate closely with aortic plaque ruptures evaluated by nonobstructive general angioscopy and can be used to better identify patients at risk of aortic plaque rupture

    This study included 101 consecutive patients who underwent nonobstructive general angioscopy (NOGA) and contrast-enhanced CT scans. On contrast-enhanced CT, the aortic wall area (AWA), aortic wall thickness (AWT), and AWA in the vascular area from the 6th to the 12th thoracic vertebral levels were evaluated. The correlation between the contrast-enhanced CT measurements and the aortic plaque ruptures detected by NOGA was assessed at the same vertebral levels. All contrast-enhanced CT findings, especially AWT and AWA, were strongly correlated with the NOGA-detected plaque ruptures. Contrast-enhanced CT may therefore be considered non-invasive imaging biomarkers to stratify patients at risk of aortic plaque rupture and to avoid unnecessary invasive diagnostic procedures.
