3D Contrast-Enhanced Ultrasound in Diagnosing Participants with Liver Cancer Undergoing Stereotactic Ablative Radiotherapy

Trial Status: closed to accrual

This pilot trial studies how well 3-dimensional (3D) contrast-enhanced ultrasound imaging works in diagnosing participants with liver cancer who are undergoing stereotactic ablative radiotherapy. Diagnostic procedures, such as 3-dimensional contrast-enhanced ultrasound, may help to determine whether perfusion characteristics (how blood flows to the liver over time) of liver metastases may be predictive of response to treatment and whether liver perfusion characteristics can be used to follow response to treatment.
