“…Centerline reconstructed images were found to have more accuracy and reproducibility in detecting abdominal aortic aneurysm, and are now endorsed by the European Society of Cardiology for detecting aortic disease [39][40][41]. Accordingly, using a centerline-based image reconstructive technique, we obtained accurate cross-sectional pan-aortic images non-invasively.…”

Aortic atherosclerosis has been linked with worse peri- and post-procedural outcomes following a range of aortic procedures. Yet, there are currently no standardized methods for non-invasive volumetric pan-aortic plaque assessment. We propose a novel means of more accurately assessing plaque volume across whole aortic segments using computed tomography angiography (CTA) imaging. Sixty patients who underwent CTA prior to trans-catheter aortic valve implantation were included in this analysis. Specialized software analysis (3mensio Vascular™, Pie Medical, Maastricht, Netherlands) was used to reconstruct images using a centerline approach, thus creating true cross-sectional aortic images, akin to those images produced with intravascular ultrasonography. Following aortic segmentation (from the aortic valve to the renal artery origin), atheroma areas were measured across multiple contiguous evenly spaced (10 mm) cross-sections. Percent atheroma volume (PAV), total atheroma volume (TAV) and calcium score were calculated. In our populations (age 79.9 ± 8.5 years, male 52 %, diabetes 27 %, CAD 84 %, PVD 20 %), mean ± SD number of cross sections measured for each patient was 35.1 ± 3.5 sections. Mean aortic PAV and TAV were 33.2 ± 2.51 % and 83,509 ± 17,078 mm(3), respectively. Median (IQR) calcium score was 1.5 (0.7-2.5). Mean (SD) inter-observer coefficient of variation and agreement for plaque area among 4 different analysts was 14.1 (5.4), and the mean (95 % CI) Lin's concordance correlation coefficient was 0.79 (0.62-0.89), effectively simulating a Core Laboratory scenario. We provide an initial validation of cross-sectional volumetric aortic atheroma assessment using CTA. This proposed methodology highlights the potential for utilizing non-invasive aortic plaque imaging for risk prediction across a range of clinical scenarios.

“…EVAR, endovascular aneurysm repair; SMA, superior mesenteric artery. cdt.amegroups.com S164 evaluation results in greater inter and intra-observer variability from reproducibility and objectivity which is heavily influenced by vessel tortuosity on axial 2D images (49,50). Sobocinski et al demonstrated that the proper utilization of a 3D workstation resulted in less type I endoleaks and secondary interventions when compared to preprocedure imaging evaluation solely by axial 2D CTA (48).…”

Imaging is a critical component of the pre-procedure evaluation and planning of endovascular aneurysm repair (EVAR). Imaging is the mainstay for proper assessment of procedural candidacy, relevant vascular anatomy, device selection, and surgical approach. Computed tomography angiography (CTA) has long been considered the preferred modality for pre-operative imaging and evaluation prior to EVAR.Recently, advances in image quality and software technology have further enhanced the proceduralist's ability to plan and perform EVAR. In this review, we highlight the current state of the art to provide interventionalists a contemporary assessment of the available tools for pre-operative imaging and evaluation prior to EVAR.

“…Measurement of aortic diameter by CTA is generally recommended with three-dimensional (3D) reconstructed images whenever possible; the maximum diameter is measured perpendicular to the centerline of the vessels on the curved multiplanar reconstruction (MPR) images [1,3].

Multidetector computed tomography (CT) has become the best modality for evaluating an aorta in the acute setting, due to its ability to rapidly detect aortic pathology with high spatial resolution. Moreover, using three-dimensional multiplanar reconstruction, CT scans can provide informative images and accurate measurements of aortic size and other anatomical landmarks. This review focuses on the CT imaging findings of aortic normal anatomy, aortic aneurysm, and the imaging spectrum of acute aortic syndrome, which includes penetrating atherosclerotic ulcer, intramural hematoma, and aortic dissection.
