目的：探讨64层螺旋CT对胃肠道间质瘤的诊断价值。方法回顾性分析30例胃肠道间质瘤（GIST）患者的临床影像及病理资料。结果30例胃肠道间质瘤中发生于胃18例，十二指肠3例，空肠3例，回肠3例，直肠3例。胃肠间质瘤向腔外型生长7例，腔内生长5例，腔内外生长18例。胃肠间质瘤CT平扫大部分显示密度不均，其可见大小不一的斑片状囊变坏死区，增强扫描肿瘤实质部分动脉期轻度强化，平衡期多为中等度强化，1例病灶有钙化，1例伴有肝转移。肿块最大径线3.0 cm～18.5 cm（平均10.2 cm）。结论胃间质瘤CT表现有一定的特征性，64层螺旋CT扫描及多平面重建有助于其定性定位诊断及良、恶性分析。

Objective To study the value of 64-slice spiral CT in the diagnosis of gastrointestinal stromal tumors(GIST).Methods Clinical,imaging and pathological data of 30 patients with GIST were collected. Results Of these 30 patients,18 were located in stomach,3 in duodenum, 3 in jejunum, 3 in ileum,3 in rectum. As for the growth pattern,these GIST patients were divided into intraluminal type(5 case),extralumind type(7 case) and mixed type(18 case ). Unenhanced CT images displayed heterogeneous density mass with patchycystic change and necrotic foci in almost 30 case,calcification in 1 case,hepatic metastasis in 1 case. Contrast enhanced CT images demonstrated mild enhancement in the arterial phase and medium enhancement in the parenchymal phase. Tumor size range from 3.0 to 18.5 cm ( mean = 10.2 cm ).Conclusion The CT imaging features of gastrointestinal stromal tumor are characteristic. 64-slice spiral CT scan and multi-planar reformation are helpful to determine the location and nature of gastrointestinal stromal tumors and their malignant and benign analysis.
