摘要
目的探索胃间质瘤64排螺旋CT图像表现特征及诊断价值研究。方法选取我院2015年1月-2018年3月收治的经手术及病理检查结果证实的胃间质瘤患者43例,患者均进行64排螺旋CT检查,并对患者的临床资料、影像学资料进行收集,分析胃间质瘤的CT图像表现特征及64排螺旋CT在胃间质瘤中的诊断价值。结果43例患者经CT检查结果显示15例良性,25例恶性,3例交界性肿瘤。23例位于胃部,9例位于小肠,8例位于结肠,3例位于肠系膜。CT平扫病灶部位呈类圆形或分叶状表现,肿块密度多数显示均匀,仅8例软组织密度影显示不均匀;CT增强扫描肿瘤于静脉期强化最为明显,且于肿块周围出现簇状小血管影,动脉期强化程度较静脉期弱。结论64排螺旋CT对胃间质瘤病灶情况显示清楚,对肿瘤的定位及诊断具有较高的临床应用价值。
Objective To explore the features and diagnostic value of 64-slice spiral CT images of gastric stromal tumor. Methods 43 patients with gastric stromal tumor diagnosed and confirmed by surgery and pathological examination in our hospital from January 2015 to March 2018 were selected. All the patients were performed 64-slice spiral CT examination. The clinical data and imaging data of patients were collected. The CT image features of gastric stromal tumors and the diagnostic value of 64-slice spiral CT for gastric stromal tumors were analyzed. Results According to the results of 43 patients’ CT examination, it showed 15 cases with benign tumor, 25 cases with malignant tumor, and 3 cases with borderline tumors. 23 cases were located in the stomach, nine cases in the small intestine, eight cases in the colon and three cases in the mesentery. In the plain CT scan, the lesions were round or lobulated, and the density of the tumors was mostly uniform, and soft tissue density shadow of only 8 cases showed unevenness. CT enhanced scanning showed the most obvious enhancement in the venous phase of the tumor, and there were clusters of small blood vessels around the tumor, and the degree of enhancement in the arterial phase was weaker than that in the venous phase. Conclusion 64-slice spiral CT clearly shows the situation of lesions of gastric stromal tumors, and it has high clinical value in the diagnosis and localization of gastric stromal tumor.
