Effectiveness of Contrast-Enhanced Ultrasound

December 22, 2025 updated by: Children's Hospital of Philadelphia

Clinical Effectiveness of Contrast-Enhanced Ultrasound in the Evaluation of Blunt Abdominal Trauma in Young Children

The 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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
