Aghayev A, et al. - During this research, CT angiography (CTA) findings of lumen contrast heterogeneity and intraluminal thrombus volume were illustrated by the experts along with an investigation of their correlation with rapid aneurysm growth in patients with abdominal aortic aneurysms (AAA) between 3 and 5 cm. The AAA CTA studies revealed intraluminal thrombus and lumen contrast heterogeneity which could be quantified. Both of these metrics demonstrated an independent link with the rapid growth rate which ought to be recognized by radiologists evaluating patients with AAA during surveillance.
