120The purpose of the study is to generate pilot data describing test characteristics of contrast enhanced ultrasound in young children with concern for abdominal trauma. The primary objective in this study is to determine the sensitivity and specificity of contrast-enhanced ultrasound (CEUS) compared to abdominal Computed Tomography (CT) in the detection of abdominal solid organ injury in young children < 8 years of age with concern for blunt abdominal trauma.
Abdominal trauma in children can be deadly, but intra-abdominal injuries can be difficult to detect and often lack external signs of injury on physical exam. The current gold standard imaging study is Computed Tomography (CT) with IV contrast, which is associated with radiation exposure. Contrast-enhanced ultrasound is a radiation-free alternative to detect abdominal injuries and has been studied primarily in adults and some older children, but evidence to support its use in young children is needed.
This is a prospective study of children less than 8 years of age who are clinically stable and undergoing an abdominal CT with IV contrast as part of their clinical care due to concerns for abdominal trauma. Investigators will compare CEUS results with those obtained by CT. Investigators will additionally include retrospective data of children who underwent both abdominal CT and CEUS as part of clinical care.
Subjects will undergo a contrast enhanced ultrasound (CEUS) during which a standard greyscale abdominal ultrasound is performed first followed by injection of intravenous contrast with Lumason, and completion of contrast-enhanced ultrasound
Comparison of CT and CEUS results from retrospective chart review of children who have had a CEUS for trauma at the Children's Hospital of Philadelphia (CHOP).
Prospective observation of comparison of CT and CEUS results among children who are undergoing a CEUS and abdominal CT as part of clinical care.
Prospective intervention using contrast enhanced ultrasound with IV contrast Lumason.
