Effect of Angiosonography to Monitor Response During Imatinib Treatment in Patients with Metastatic Gastrointestinal Stromal Tumors

Abstract
Purpose: Gastrointestinal stromal tumor (GIST) metastases are typically intra-abdominal and hypervascular. We assessed the effect of angiosonography with a second-generation contrast agent to monitor response during imatinib treatment in patients with metastatic KIT+ GIST.
