This study evaluates the ability of contrast-enhanced ultrasound to improve the diagnosis of acute appendicitis in children compared to conventional ultrasound.
Acute appendicitis is the most common surgical emergency in children. Diagnostic evaluation for possible appendicitis frequently leads to imaging studies. Magnetic resonance imaging (MRI) and computed tomography (CT) are currently the gold-standard techniques for the diagnosis or exclusion of acute appendicitis. However, these methods not always immediately available; may require administration of intravenous contrast material with the potential for allergic reactions and nephrotoxicity; and, in the case of CT, requires the administration of ionizing radiation that is linked to the long-term development of radiation-induced cancers. The current study will evaluate a potentially safer, radiation-free diagnostic method for acute appendicitis, using contrast-enhanced ultrasound to provide a more accurate means of visualizing the appendix than conventional US imaging.
Exclusion Criteria:
IV sulfur hexafluoride lipid-type A microspheres, 0.03 mL/kg, 2 doses per examination, total dose not to exceed 4.8 mL. Single examination per patient.
Drug: Sulfur hexafluoride lipid-type A microspheres
Contrast-enhanced US imaging of the appendix
Also known as: Lumason
Contrast-enhanced ultrasound diagnosis of acute appendicitis
