| 目的 探讨MSCT特征在评价胃肠道间质瘤(GIST)恶性程度中的价值。 方法 收集44例首次接受增强CT检查、并经手术病理确诊为GIST的患者资料,分析不同恶性程度GIST的CT表现差异。 结果 病理诊断极低度恶性GIST 5例,低度恶性9例,中度7例,高度23例。不同恶性程度的GIST在病灶大小、病灶部位、生长方式、强化方式、边界、系膜脂肪浸润、坏死囊变、肿瘤血管及侵犯周围器官等CT特征方面的差异均有统计学意义(P均<0.05)。 结论 肿瘤大小、病灶部位、生长方式、强化方式、边界、系膜脂肪浸润、坏死囊变、肿瘤血管及侵犯周围器官等CT特征对于判断GIST的恶性程度具有重要价值。 |

| Objective To explore the value of MSCT features in predicting the malignancy degree of gastrointestinal stromal tumor (GIST). Methods CT Data of 44 patients with pathologically proved GIST were reviewed. The differences of CT features among different malignancy degrees of GIST were analyzed. Results Pathology confirmed very low malignancy GIST in 5 patients, low malignancy in 9, moderate malignancy in 7 and high malignancy in 23. The tumor size, location, growth pattern, enhancement pattern, contour, mesenteric fat infiltration, cystic-necrosis, tumor vascularization and direct organ invasion had statistical differences among different malignancy degrees (all P<0.05). Conclusion Tumor size, location, growth pattern, enhancement pattern, border, mesenteric fat infiltration, cystic-necrosis, tumor vascularization and direct organ invasion might be predictive indexes for malignancy of GIST. |
