Abstract
Objective
To compare Agatston with Ordinal Scores for the extent of coronary artery calcification
(coronary artery calcium) using nongated low-dose computed tomography (CT) scans.
Materials and Methods
A total of 631 asymptomatic participants had CT scans from 2010 to 2013. Their Ordinal
and Agatston Score were classified into categories.
Results
The Ordinal Score Categories showed excellent agreement (weighted kappa of 0.83; 95%
confidence interval: 0.79–0.88) with the Agatston Score Categories.
Conclusions
The use of the Ordinal Score is readily obtained on low-dose CT scans that are used
for CT screening for lung cancer and these scores are useful for risk stratification
of coronary artery disease.
