The objective of this study is to compare a graph-matching-based software and a conventional tool for postprocessing of computed tomography angiography (CTA) in correlation with the gold standard digital subtraction angiography. Sensitivity, specificity, accuracy, and interobserver agreement increased from 80.3% to 92.9%, from 69.1% to 92.4%, from 73.5% to 92.8%, and from 0.45 to 0.96, respectively, using the graph-matching-based technique. Graph-matching-based CTA increases sensitivity, specificity, accuracy, and interobserver agreement in comparison to a conventional bone elimination tool in the assessment of peripheral arterial occlusive disease.
本研究旨在比较基于图形匹配的软件和传统的计算机断层血管造影(CTA)后处理工具与金标准数字减影血管造影的相关性。使用基于图形匹配的技术,敏感性、特异性、准确性和观察者间一致性分别从 80.3%增加到 92.9%、从 69.1%增加到 92.4%、从 73.5%增加到 92.8%和从 0.45 增加到 0.96。与传统的骨消除工具相比,基于图形匹配的 CTA 可提高评估外周动脉阻塞性疾病的敏感性、特异性、准确性和观察者间一致性。
