Abstract

Our objective was to determine the MDCT appearance of gastrointestinal stromal tumors (GISTs) after treatment with imatinib mesylate. Cystic changes within primary and metastatic GISTs seen on MDCT in patients after imatinib mesylate therapy are evidence of disease response. Calcification may also occur in lesions that respond to therapy.
