RESUMEN
Objective To investigate the security,applicability and diagnostic capacity of intravenous contrast-enhanced ultrasound (CEUS) in a pediatric population. Methods A total of 53 pediatric patients (8 months to 18 years old) received 66 intravenous applications of ultrasound contrast agent SonoVue.Side effects were documented.Histology,reference imaging or clinical diagnosis were compared with CEUS diagnostic results. Results Adverse effects occurred in 1/66 applications (1.5% ). For 44 focal liver lesions,the sensitivity was 100%,the specificity was 95.65%,the positive predictive value was 95.45% and the negative predictive value was 100%.The diagnostic accuracy was 97.73%.All 22 other lesions were diagnosed correctly.Conclusions It is safe and feasible to use intravenous CEUS in children.CEUS is worthy of promotion in pediatric patients with abdominal diseases.
