Frequently asked questions
Coronary artery z-score (Kawasaki syndrome): What does this calculator compute?
Calculates the body-surface-area-based z-score of a coronary artery internal diameter using the equations of Dallaire & Dahdah 2011 (Montreal, 6 segments), McCrindle 2007 (Boston) or Olivieri 2009 (Washington) and classifies it according to AHA 2017: no involvement, dilation, small, medium or large aneurysm.
