目的：探讨多层螺旋CT增强扫描对消化道间质瘤的诊断价值。方法：回顾性分析经手术病理证实的46例GIST(gastrointestinal stromal tumors)患者影像资料，并与临床及病理表现对照。所有患者均行MSCT平扫及增强扫描。结果：46例胃肠道间质瘤中位于胃24例，十二指肠6例，空回肠10例，腹腔网膜3例，食道2例，结肠1例。肿块向腔外生长者居多，多呈圆形或类圆形。肿瘤直径1-17c m不等，肿瘤大于5.0c m者多有中心或偏侧坏死区，且与周围组织境界不清时考虑肿瘤恶变。多数病灶增强动脉期明显不均匀强化，静脉期呈持续明显强化。46例中恶性27例，其中1例伴肝转移，1例伴有腹腔转移。结论：MSCT可以很好的显示消化道间质瘤的部位、大小、形态及内部结构，定位准确率高,高度恶性定性准确,可为临床诊治GIST 提供详细的依据。

Objective To investigate the value of multislice CT ( MSCT) enhanced scanning in the diagnosis of gastrointestinal stromal tumors(GIST).Methods CT imaging data of 46 patients with GIST confirmed by surgery and pathology were retrospectively analysed and compared with the clinic presentations and pathological findings.Al patients were underwent plain and enhenced scan with MSCT. Results In 46 cases of gastrointestinal stromal tumors in stomach 24 cases, 6 cases of duodenum, ileum 10 cases, abdominal omentum 3 cases, 2 cases of esophagus, colon in 1 case. Bump to the cavity exogenous mostly elderly, formed a round or oval. Tumor diameter range 1-17 cm, many more than 5.0 cm center or partial necrosis area, boundary is not clear to consider and with the surrounding tissue tumor progression. Most lesions enhanced obviously uneven arterial enhancement, venous phase continue to strengthen significantly. 46 cases of malignant 27 cases, including 1 case with liver metastasis, 1 case with peritoneal metastasis. Conclusion MSCT can wel display the part of the gastrointestinal stromal tumor, size, shape and internal structure, high positioning accuracy, high malignant qualitative accurately, can provide detailed basis for clinical treatment of GIST.
