Study Arms:
- Contrast-enhanced Ultrasonography (Type: EXPERIMENTAL): Intravenous administration of contrast agent Sulfur hexafluoride lipid-type A microspheres before performing contrast-enhanced ultrasound (CEUS). In pediatric patients, after reconstitution 0.03 mL per kg is administered intravenously. The weight-based dose of 0.03 mL per kg will be repeated one time during a single examination. Following each injection, an intravenous flush of 0.9% Sodium Chloride is injected. The study duration per subject will be approximately 15 minutes including the time to prepare the contrast agent and perform the CEUS, as well as the 60 minute monitoring period after the first and second injection (if there are two injections of contrast) of the contrast agent.

Based on this trial design, predict the completion outcome and termination type (if applicable).
