Diameters of aneurysm sacs during surveillance after endovascular abdominal aortic aneurysm (AAA) repair are shown in 114 data points from 75 patients comparing computed tomography (CT, y axis) and duplex ultrasound (DU; x-axis) scans performed ≤1 month of each other. The Pearson correlation coefficient was 0.956, which was statistically significant (P < .001).

Follow-up charges for group 1 (black bars) and group 2 (gray bars) are compared based on 2008 health care system pricing (y axis) per patient for each year of follow-up (x axis) after endovascular aneurysm repair and are not cumulative.
