Abstract: To evaluate the value of dual source CT(DSCT) in diagnosis of coronary artery lesions due to kawasaki disease in children. MethodsFifteen children with known kawasaki disease and coronary artery lesions confirmed by echocardiography underwent coronary artery angiography by DSCT. The number, location, shape and size of each coronary artery aneurysm was recorded and compared with those determined by echocardiography. ResultsThere were 8 males and 7 females with a mean age of 3 years and 2 months (range 2 months to 11 years). A total of 43 coronary artery aneurysms were found by DSCT, and the maximum diameter of which was 1.55cm (mean 0.65±0.47cm). 15 aneurysms were small in size, 20 aneurysms were medium in size and 8 were giant aneurysms. Among the aneurysms in the left coronary artery, 9 were located in the left main trunk, 4 were located in the proximal segment of the left anterior descending branch(LAD), 5 were located in the medium segment of the LAD, and 3 were located in the left circumflex branch. 22 coronary artery aneurysms were located in the right coronary artery, including 9 in the proximal segment, 7 in the medium segment and 6 in the distal segment. 3 stenotic segments and 2 thrombus were additionally found. 6 aneurysms located in the medium or distal segments, 3 stenotic and 2 thrombus were not found by echocardiography. ConclusionDSCT can clearly visualize coronary artery lesions due to kawasaki disease in children, especially in detection of the stenotic segments and thrombosis.
