Contrast-enhanced ultrasound can safely improve the diagnosis of a variety of medical conditions in children, according to a study by researchers at Jena University Hospital, Germany. In the study, researchers used contrast-enhanced ultrasound to image 50 paediatric patients. They found that the procedure was not associated with any adverse safety events in children, and they were able to successfully differentiate between a benign cyst and a perfused tumour. According to the researchers, unlike CT and nuclear imaging, contrast-enhanced ultrasound does not expose patients to ionising radiation, and it can be used to assess kidney infections, organ blood flow and internal abdominal injuries. The researchers have called for additional clinical trials to validate the use of contrast-enhanced ultrasound in paediatric patients.
