The main questions it aims to answer are:\n\n* Is intravenous contrast-enhanced ultrasound helpful for the diagnosis of intra-abdominal diseases in children?\n* What medical problems do participants have when participating in intravenous contrast-enhanced ultrasound examination?\n* How can ultrasound doctors conduct intravenous contrast-enhanced ultrasound examinations in a standardized manner? Researchers will performing intravenous contrast-enhanced ultrasound examinations on participants and collecting research subjects to establish a multicenter clinical data database.\n\nParticipants will:\n\n* Perform abdominal ultrasound examination to assess the condition.\n* At least conduct one intravenous contrast-enhanced ultrasound examination. Based on the result of the contrast examination, decide whether to conduct another examination.\n* Keep a diary of their symptoms and therapeutic process in 30 days.",[79,80,81],"Abdominal Neoplasm","Abdominal Injury","Ascites","2025-12-05",{"date":84,"type":85},"2025-12-08","ACTUAL",{"date":87,"type":85},"2024-09-10",{"date":89,"type":75},"2026-09-30",{"name":5,"class":6},1]
