Assessment of coronary artery abnormalities by multislice spiral computed tomography in adolescents and young adults with Kawasaki disease.

Multislice spiral computed tomography was performed in 16 adolescents and young adults who had Kawasaki's disease to assess coronary artery abnormalities. Adequate images were obtained for 96% of major coronary segments. The sensitivity of multislice spiral computed tomography to detect coronary artery aneurysms was 100%, and that for significant stenoses and occlusions was 87.5%, whereas false-positive results due to severe calcification was present in 5 arteries and those due to cardiac motion artifact were present in 2, resulting in a specificity of 92.5%.
