Abstract
This pictorial review illustrates CT and MR imaging appearance of gastrointestinal stromal tumor (GIST) of the stomach and other lesions with similar imaging appearance. GIST of the stomach appears as well-defined enhanced masses with characteristics of subeppthial neoplasms. Majority are exophytic growth, but can also be of intra-luminal growth. GIST can growth into a large mass without gastrointestinal tract obstruction. Necrosis is often seen in GIST and results in heterogeneous enhancement and communication with gastrointestinal tract. CT and MRI features of several other neoplasms mimicking GISTs in the stomach are also described in this review.
摘要
本影像学综述展示了胃的胃肠道间质瘤（GIST）和其他具有相似影像学表现的病变的 CT 和 MR 成像表现。胃 GIST 表现为边界清楚的强化肿块，具有黏膜下肿瘤的特征。大多数为外生性生长，但也可以是腔内生长。GIST 可以在没有胃肠道梗阻的情况下生长为巨大肿块。坏死在 GIST 中很常见，导致不均匀强化并与胃肠道相通。本综述还描述了几种在胃中模拟 GIST 的其他肿瘤的 CT 和 MRI 特征。
