| 目的 探讨多层螺旋CT(MSCT)三维重建技术对胃肠间质瘤危险度的预测价值。方法 收集经手术病理证实的20例间质瘤病人资料,依据危险度分为潜在恶性组和恶性组,所有病人均于术前行腹部MSCT检查并结合多平面三维重建,观察影像学征象,包括肿瘤位置、直径大小、生长方式、形态、轮廓、坏死、转移和钙化情况,比较两组间差异。结果 两组间相比较,在肿瘤的直径大小、形态、轮廓、坏死和转移方面差异有统计学意义(P＜0.05),而在肿瘤生长位置、生长方式和钙化方面差异无统计学意义(P＞0.05)。结论 MSCT三维重建显示胃肠间质瘤具有定位准确,观察清晰的优势,其直径大小、形态、轮廓、坏死和转移的影像学征象可以预测胃肠间质瘤的危险度,为临床提供良好的参考价值。 |

| Objective To investigate the value of 3-dimensional reconstruction of multislice spiral CT in predictingrisk stratification of gastrointestinal stromal tumor.Methods The 20 postoperative histologically confirmed cases were assigned into potential malignancy group and malignancy group according to the risk stratification.All of the patientsunderwent 3-dimensional reconstruction of multislice spiral CT (MSCT).Their CT features were observed and compared between the two groups,including tumor location,tumor size,growth pattern,tumor shape,tumor contour,tumor necrosis,metastasis and calcification.Results There werestatistically significant differences between the two groups in tumor size,shape,contour,necrosis and transfer (P<0.05),while there were no significant differences in tumor location,growth pattern and calcification(P>0.05).Conclusions 3-dimensional reconstruction of multislice spiral CT has the advantages of accurate positioning and clear observation for imaging GIST,in which the features of tumor size,shape,contour,necrosis and transfer can predict the risk stratification of GIST,thus provides a good reference value for clinics. |
