Repeatability of AI-based, automatic measurement of vertebral and cardiovascular imaging biomarkers in low-dose chest CT: the ImaLife cohort.

Department of Radiology, University of Groningen, University Medical Center of Groningen, Groningen, The Netherlands.
Objective: To evaluate the repeatability of AI-based automatic measurement of vertebral and cardiovascular markers on low-dose chest CT.
Methods: We included participants of the population-based Imaging in Lifelines (ImaLife) study with low-dose chest CT at baseline and 3-4 month follow-up. An AI system (AI-Rad Companion chest CT prototype) performed automatic segmentation and quantification of vertebral height and density, aortic diameters, heart volume (cardiac chambers plus pericardial fat), and coronary artery calcium volume (CACV).

Notably, the C-X-C Motif Chemokine Ligand 12/C-X-C Chemokine Receptor Type 4 (CXCL12/CXCR4) signalling pathway's activation is markedly increased in a mouse model of abdominal aortic aneurysms (AAA). Nonetheless, the precise contribution of this pathway to AAA development remains to be elucidated. The AAA mouse model was induced by local incubation with elastase and oral administration of β-aminopropionitrile.

Introduction And Importance: Internal iliac artery aneurysms repair represents a life-threatening condition due to their anatomical position and the risk of rupture. Iliac branch devices are strongly recommended for anatomically suitable patients, but limited alternatives exist when their use is unsuitable. The use of custom-made fenestrated endografts is well documented in other aortic territories, however, their application for the treatment of internal iliac artery aneurysm remains limited.

Infectious aneurysms represent <5 % of cases [1] with a crucial and challenging diagnosis. Staphylococcus, Streptococcus, Enterobacteria are mostly involved but unusual pathogens like Listeria monocytogenes can be responsible. Collecting data of these rare situations allows to improve diagnosis.

Purpose: Monocyte chemoattractant protein-1 (MCP-1/CCL2) plays a key role for infiltration of monocytes/macrophages and studies have demonstrated that the MCP-1/C-C chemokine receptor 2 (CCR2) axis might be involved in the pathogenesis and progression of abdominal aortic aneurysms (AAA). Molecular imaging has shown potential for human clinical research studies. We evaluated the expression of CCR2 in patients with small AAA using single-photon emission computed tomography (SPECT) with the technetium-99m-6-hydrazinylnicotinoyl-C-C-chemokine receptor-2 ligand (Tc-HYNIC-CCR2-L).
