冠脉钙化积分(Coronary Artery Calcification Score, CACS)是使用CT对冠脉整体的钙化情况进行量化评估,目前常用的计算方法有Agatston积分、体积积分和质量积分。 Agatston积分是目前最常用的钙化积分,也是绝大多数医院影像报告中出现的积分。Agatston积分计算的原理为钙化密度赋分×钙化面积。...

Materials and methods: We use a database of 5973 non-contrast non-ECG gated chest CT scans where the Agatston score has been manually computed. The heart of each scan is cropped automatically using an object detector. The database is split in 4973 cases for training and 1000 for testing. ...

Agatston评分是一种半自动化工具,可通过未经增强的低剂量CT扫描检测进行冠状动脉钙化评分(coronary artery calcification score, CACS),该扫描通常在接受冠脉CT检查的患者中进行[7]。Agatston积分是根据CT扫描断层下冠状动脉钙化的体积大小以及密度大小进行评分,如在Agatston...
