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.
胃のGISTは、subeppthial腫瘍の特徴による明確な強化された腫瘤の外観を呈する。
大多数は外方増殖性腫瘍であるが、腔内腫瘍でもありえる。
胃腸管閉塞のない大きな腫瘤へのGIST缶発育。
壊死は、消化管で異種起源強化と連絡でGISTと結果でしばしば見られる。
CTと胃でGISTを模倣しているいくつかの他の腫瘍のMRI特徴は、この総説でも記述される。
