title: Coronary calcium scan acquisition before coronary CT angiography: limited benefit or useful addition?
abstract: OBJECTIVE
  This article reviews the role of coronary calcium quantification in symptomatic patients and the pros and cons of acquiring an unenhanced coronary calcium scan in every patient with suspected coronary artery disease referred for coronary CT angiography.
  
  
  CONCLUSIONS
