Key Points

To evaluate the imaging characteristics and diagnostic accuracy of FDG-PET/CT, contrast-enhanced CT, and combined imaging in differentiating mycotic, inflammatory, and non-infected abdominal aortic aneurysms.
Evaluated imaging characteristics from FDG-PET/CT, contrast-enhanced CT, and combined modalities in patients with suspected mycotic or inflammatory abdominal aortic aneurysms.
Identified distinct imaging characteristics on PET/CT and contrast-enhanced CT that aid in differentiating mycotic abdominal aortic aneurysms from inflammatory abdominal aortic aneurysms.
Demonstrated qualitative differences allowing differentiation between infected or inflammatory aneurysms and standard non-infected, non-inflammatory abdominal aortic aneurysms.

Implication

Reveals imaging features of FDG-PET/CT and contrast-enhanced CT distinguish infected from inflammatory aortic aneurysms, indicating potential diagnostic utility.

Abstract

Specific imaging characteristics of PET/CT and CE-CT may be helpful in differentiating between MAA, IAA, and non-infected, non-inflammatory AAA.
