Calcium scoring and CT angiography

UCSF Radiologist Dr. Brett Elicker describes how calcium scoring and CT angiography (CTA) work together to diagnose coronary artery disease.

CT for Coronary Artery Disease 

Coronary Calcium Screening

  • No contrast
  • Looks only for calcium
  • Doesn’t asses for blockage
  • Risk factor stratification

Coronary CT angiography

  • Intravenous contrast
  • Looks for blockage
  • Only used in people with symptoms
  • Negative CT->symptoms not from CAD
  • Positive CT->proceed to cardiac catheterization
