This test is similar to a bone scan, but a slightly radioactive sugar is injected into the blood. Tumors use more of this sugar than normal cells, so the radiation collects in tumors, where it can be seen with a special camera. PET scans can help determine the spread of Ewing's tumors, find out if abnormal areas seen on a bone scan or CT scan are tumors, and help follow the response of the tumor to treatment.
These tests can help show where the tumor is and whether it has spread. They may give enough information for a doctor to tell the cause of the problem, or you may need further testing.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
