Article Title: Quantification of abdominal aortic calcification using photon-counting CT angiography: an imaging biomarker for high-risk cardiovascular patients
doi: 10.1007/s11547-025-01978-0
Figure Lengend Snippet: Research design. Calcification in the abdominal aortic wall was extracted from 3D CTA images and aortic calcification volume (ACV) was measured. In addition, the aortic wall was constructed from 3D CTA images with VNCa applied and aortic wall volume (AWV) was measured. Percentage calcification volume (PCV) is the ratio of ACV to AWV. Coronary artery calcification was quantified using a dedicated workstation to calculate the Agatston score. Using the Agatston score indicators as outcomes, we investigated the relationship between ACV and PCV and attempted to define the severity of abdominal atherosclerosis. CTA = CT angiography; VNCa = virtual non-calcium
Article Snippet: Quantification of ACV and its proportion in the AWV was performed by the radiologist A and another one radiologist B (12-year experience in abdominal imaging) using a 3D image analysis system (SYNAPSE VINCENT version 6.7; Fujifilm, Tokyo, Japan) on the abdominal 3D CTA images using the VNCa algorithm.
