摘　　要：目的探讨经口服超声造影彩色多普勒对胃间质瘤的诊断作用。方法回顾性分析2006年5月～2008年5月间经口服超声造影诊断并经病理证实的44例胃间质瘤的声像表现。结果口服超声造影彩色多普勒能清晰地显示胃壁的层次结构,显示胃间质瘤的发生部位。胃间质瘤以腔外型生长为主,多发生于胃体、底部。良性肿瘤直径均值(45.00±27.00)mm,RI值(0.52±0.14)。恶性肿瘤直径均值(98.00±21.90)mm,RI值(0.72±0.14)。良、恶性肿瘤瘤体形态、边界、回声分布、大小、阻力指数差异有显著性(P<0.05),交界性肿瘤的超声表现介于两者之间。结论经口服超声造影彩色多普勒超声对胃间质瘤的诊断及良恶性鉴别有重要价值。[Objective] To evaluate the value of color Doppler sonography and oral contrast ultrasonographyic in the diagnosis of gastric stromal tumors. [Methods] The sonographie characteristic of 44 patients with gastric stromal tumors confirmed by pathology were analyzed retrospectively. [Results] Stomaeh wall and Space- Oeeupying lesion were showed distinctly by color Doppler sonography and oral eontrast ultrasonographyie, Most tumors occurred in gastrie corpus or gastric fundus, out of the gastie cavity. In benign tumors,the average diameter was （45.00±27.00） mm and RI was （0.52＋0.14）, while diameter （98.00±21.90） mm, RI （0.72±0.14） in malignant tumor. There was significant difference in tumor size, shape, inner echo pattern, border and RI between the benign and the malignant （P 〈0.05）. And borderline tumor showed between the benign and the benign. [Conclusion] Color Doppler sonography and oral contrast uhrasonographyie play a role in diagnosis of gastric stromal tumors.
