Abstract

Gastrointestinal stromal tumors (GISTs) account for the majority of gastrointestinal mesenchymal tumors. Recent advances in treatment using the molecular targeting agent imatinib mesylate have shown startling response rates and variegated imaging findings. We present the various imaging appearances of GIST on computed tomography (CT) and magnetic resonance imaging (MRI), both before and after treatment.

摘要

胃肠道间质瘤（GISTs）占胃肠道间叶性肿瘤的大多数。使用分子靶向药物甲磺酸伊马替尼治疗的最新进展显示出惊人的缓解率和多样的影像学表现。我们展示了GIST在治疗前后的计算机断层扫描（CT）和磁共振成像（MRI）上的各种影像学表现。
