title: Coronary artery calcification on low-dose computed tomography: comparison of Agatston and Ordinal Scores.
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.
  
  
  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.
