“…Dual-source computed tomography was shown to have a sensitivity of 85% and specificity of 84% compared with IVUS. 27 Some small pediatric studies have suggested the feasibility of multidetector computed tomography in both Kawasaki disease and CAV, but issues of resolution, high heart rates, and ionizing radiation exposure 28,29 Indirect imaging with dobutamine stress echocardiography has also been used in children to diagnose CAV. [30][31][32] However, validation against IVUS in children is lacking.…”

Background-Coronary allograft vasculopathy is the leading cause of late death after heart transplantation in children. It is poorly detected by conventional angiography. Intravascular ultrasound is invasive and costly. This study shows that magnetic resonance imaging (MRI) late gadolinium enhancement (LGE) of the coronary vessel wall can detect and grade coronary allograft vasculopathy. Methods and Results-Twenty-four children (10 male; age range, 9-17 years) underwent coronary angiography, intravascular ultrasound, and MRI.

“…Electrocardiogram (ECG)-gated scans, especially retrospective ECG-gated scans, have been used to evaluate coronary artery lesions in children with KD [2,9]. The high radiation dose required remains the main concern [10]; even though dose-saving methods including low tube potential, tube current modulation and body sizeadapted CT protocols have been adopted, the effective radiation dose is still high at up to 2.17-3.14 mSv [11][12][13].…”

Objectives: The aim of this study was to prospectively evaluate the initial application and value of prospective electrocardiogram (ECG)-triggered dual-source CT coronary angiography (DSCTCA) in the diagnosis of infants and children with coronary artery aneurysms due to Kawasaki disease. Methods: 19 children [12 males; mean age 13.47 months, range 3 months to 5 years; mean heart rate 112 beats per minute (bpm), range 83-141 bpm] underwent prospective ECG-triggered DSCTCA with free breathing. Subjective image quality was assessed on a five-point scale (1, excellent; 5, non-diagnostic) by two blinded observers. The location, number and size of each aneurysm were observed and compared with those of transthoracic echocardiography (TTE) performed within 1 week. Interobserver agreement concerning the subjective image quality was evaluated with Cohen's k-test. Bland-Altman analysis was used to evaluate the agreement on measurements (diameter and length of aneurysms) between DSCTCA and TTE. The average effective dose required for DSCTCA was calculated for all children. Results: All interobserver agreement for subjective image quality assessment was excellent (k50.87). The mean¡standard deviation (SD) aneurysm diameter with DSCTCA was 0.76¡0.36 cm and with TTE was 0.76¡0.39 cm. The mean¡SD aneurysm length with DSCTCA was 2.06¡1.35 cm and with TTE was 2.00¡1.22 cm. The BlandAltman plot for agreement between DSCTCA and TTE measurements showed good agreement. The mean effective dose was 0.36¡0.06 mSv. Conclusion: As an alternative diagnostic modality, prospective ECG-triggered DSCTCA with excellent image quality and low radiation exposure has been proved useful for diagnosing infants and children with coronary artery aneurysms due to Kawasaki disease. Advances in knowledge: Prospective ECG-triggered DSCTCA for infants and children allows rapid, accurate assessment of coronary aneurysms due to Kawasaki diseases, compared with TTE.

“…2). Although the image quality in children with a high heart rate and affected breathing is not as excellent as that in adults or adolescents, the majority of aneurysms are still well detected because they mainly affect the proximal and middle segments of coronary arteries (Peng et al 2009). It is more sensitive than echocardiography for the detection of aneurysms located on the distal segments of the coronary arteries (Chu et al 2006) and can also estimate the degree of stenosis with precision.…”
