Brief summary
St. Jude Children's Research Hospital is studying ways to make ultrasound images clearer - to be able to see blood vessels, body structures, and tumors better. Ultrasound uses sound waves to create pictures, allowing doctors and other medical professionals to see inside the body. Researchers are studying a contrast agent (like a dye) called Optison™. St. Jude Children's Research Hospital researchers want to learn the best and safest dose of this ultrasound dye.
Interventions
DRUGOptison
Intervention description: Based on recommendation by the FDA, we began with a dose of 0.125ml/m\^2 and escalated at 0.15 ml/m\^2 increments, to 0.275 ml/m\^2 and 0.425ml/m\^2 and 0.500ml/m\^2. We will now continue to escalate the dose of Optison at 0.300ml/m\^2 increments to a maximum single dose of 4ml or a total cumulative dose of 8.7 ml as recommended by the manufacturer.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To learn the best dose of Optison™ ultrasound contrast agent that can be safely given to children with abdominal or pelvic tumors. | Unknown-study temporarily closed. |
| To learn the effects (good and bad) of using Optison during ultrasound. | Unknown-study temporarily closed. |
| To learn if using Optison™ during ultrasound can show the size and location of a tumor, how the tumor is responding to chemotherapy, and whether it has moved into surrounding tissue. | Unknown-study temporarily closed. |
