Figure 3.
Serial CTA images in one patient demonstrate luminal contrast attenuation that is (A) homogeneous at initial CTA but (B) becomes visibly inhomogeneous at 12 months (AAA Contrast Inhomogeneity=0.6) and (C) further increases at 39 months (AAA Contrast Inhomogeneity=0.86). Anterior thrombus formation and aneurysm growth at the region corresponding to the observed inhomogeneity in attenuation is noted over time.
