目的探讨多层螺旋CT(MSCT)对胃肠道间质瘤(GIST)的诊断价值。方法回顾性分析31例经手术病理证实的GIST的MSCT资料。结果 31例中,肿瘤位于胃部19例、小肠8例、结肠3例、肠系膜1例。病理诊断:7例良性GIST,8例交界性GIST,16例恶性GIST。主要CT表现为圆或类圆形肿块影,良性肿块边缘较清晰,恶性边界不清,部分边缘呈分叶状。平扫密度较为均匀。增强后肿瘤实质部分强化较为明显。结论 CT可作为GIST的常规检查方法,可对肿瘤进行准确定位,有助于判断GIST的性质,指导临床治疗和预后评估。
Objective To investigate the diagnostic value of multislice spiral CT (MSCT) in gastrointestinal stromal tumors (GIST). Methods A retrospective analysis of 31 cases of pathologically confirmed GIST MSCT data. Results Of the 31 cases, 19 were located in the stomach, 8 in the small intestine, 3 in the colon, and 1 in the mesentery. Pathological diagnosis: 7 cases of benign GIST, 8 cases of borderline GIST, 16 cases of malignant GIST. The main CT showed round or oval mass, benign lumps more clear edge, malignant border is unclear, part of the edge was lobulated. Flattening density is more uniform. After the enhancement of the tumor part of the more obvious enhancement. Conclusion CT can be used as a routine examination method of GIST, which can accurately locate the tumor, and help to determine the nature of GIST and guide the clinical treatment and prognosis evaluation.
