Ultrasound breakthrough: predicting cancer therapy success without needles

This study is testing whether a special type of ultrasound (called D-CEUS) can predict if a targeted radiation therapy (PRRT) is working in people with advanced neuroendocrine tumors of the pancreas or gut. About 30 adults with these tumors will get D-CEUS scans before, during, and after PRRT to see if changes in blood flow patterns can tell doctors early on who is responding. The goal is to find a non-invasive way to monitor treatment, avoiding unnecessary side effects for those who are not benefiting.
