Quantitative evaluation of coronary artery wall echogenicity by integrated backscatter analysis in Kawasaki disease.

Background: Coronary artery wall echogenicity increases on echocardiograms during the acute phase of Kawasaki disease (KD). According to this background, echogenicity of the coronary artery wall in patients with KD is quantified by using integrated backscatter (IB) analysis.

Methods: IB analysis is a quantitative method for evaluating echogenicity.
