“…21 Strain estimation based on 2D-US measurements has been developed for cardiology 14 and has already been used to calculate the strain of AAA in preliminary studies. 10,11 But the accuracy of such estimates remain unverified.…”

“…On the other hand, ultrasound (US)-based aneurysm surveillance is a non-invasive, radiation-free, cheap and reproducible method. 9 However, there have been few US studies of the biomechanical wall properties of AAA reported in the literature, 10,11 as well as few studies showing the use of three-dimensional ultrasound (3D-US) imaging to evaluate aneurysm volume quantification. 12,13 The aim of this study was to assess the ability of the US coupled with two-dimensional (2D) speckle-tracking algorithms to evaluate biomechanical properties of the aorta in patients with and without AAA.…”

The objective was to demonstrate the ability of ultrasound (US) with 3D properties to evaluate volumetry and biomechanical parameters of the aorta in patients with and without abdominal aortic aneurysm (AAA). Thirty-one patients with normal aortas (group 1), 46 patients with AAA measuring 3.0-5.5 cm (group 2) and 31 patients with AAA ⩾ 5.5 cm (group 3) underwent a 2D/3D-US examination of the infra-renal aorta, and the images were post-processed prior to being analyzed. In the maximum diameter, the global circumferential strain and the global maximum rotation assessed by 2D speckle-tracking algorithms were compared among the three groups. The volumetry data obtained using 3D-US from 40 AAA patients were compared with the volumetry data obtained by a contemporary computed tomography (CT) scan. The median global circumferential strain was 2.0% (interquartile range (IR): 1.0-3.0), 1.0% (IR: 1.0-2.0) and 1.0% (IR: 1.0-1.75) in groups 1, 2 and 3, respectively (p < 0.001). The median global maximum rotation decreased progressively from group 1 to group 3 (1.38º (IR: 0.77-2.13), 0.80º (IR: 0.57-1.0) and 0.50º (IR: 0.31-0.75), p < 0.001). AAA volume estimations by 3D-US correlated well with CT (R 2 = 0.76). In conclusion, US with 3D properties is non-invasive and has the potential to evaluate volumetry and biomechanical characteristics of AAA.

“…Three-dimensional ultrasound imaging systems are useful when measuring aneurysm length, diameter, and volume [52, 53]. Dynamic properties of vessels can also be measured by ultrasound using M-mode or other tracking features [54], thus obtaining additional information about the distensibility of aneurysms [55]. Tissue Doppler imaging is an ultrasound technique that can measure in vivo wall motion along an arterial segment [45, 56–59].…”

Current laboratory research in the field of abdominal aortic aneurysm (AAA) disease often utilizes small animal experimental models induced by genetic manipulation or chemical application. This has led to the use and development of multiple high-resolution molecular imaging modalities capable of tracking disease progression, quantifying the role of inflammation, and evaluating the effects of potential therapeutics. In vivo imaging reduces the number of research animals used, provides molecular and cellular information, and allows for longitudinal studies, a necessity when tracking vessel expansion in a single animal. This review outlines developments of both established and emerging molecular imaging techniques used to study AAA disease. Beyond the typical modalities used for anatomical imaging, which include ultrasound (US) and computed tomography (CT), previous molecular imaging efforts have used magnetic resonance (MR), near-infrared fluorescence (NIRF), bioluminescence, single-photon emission computed tomography (SPECT), and positron emission tomography (PET). Mouse and rat AAA models will hopefully provide insight into potential disease mechanisms, and the development of advanced molecular imaging techniques, if clinically useful, may have translational potential. These efforts could help improve the management of aneurysms and better evaluate the therapeutic potential of new treatments for human AAA disease.

“…No entanto, há apenas alguns estudos na literatura que demonstram, através do US, características biomecânicas da parede dos AAA. 28,29 Da mesma forma, existem poucos estudos que mostram o uso do ultrassom tridimensional (US-3D) para quantificação do volume de aneurismas. [30][31][32] Dessa forma, é evidente a necessidade de introduzir na prática clínica um método não invasivo que mostre características individuais dos AAA.…”
