概括
计算机断层扫描 (CT) 标准现在可以区分胃肠外 stromal 瘤 (eGISTs) 和腹内纤维化 (IAF). 关键指标包括病变位置,轮,增强模式和大小,有助于准确诊断.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 胃肠病学 胃肠病学
背景情况:
- 区分胃肠外层瘤 (eGISTs) 和腹内纤维瘤 (IAF) 对于适当的患者管理至关重要.
- 计算机断层扫描 (CT) 是评估腹部质量的主要成像方式.
研究的目的:
- 确立最终的计算机断层扫描 (CT) 标准,以区分胃肠外 stromal 瘤 (eGIST) 和腹内纤维瘤 (IAF).
主要方法:
- 从31个病理确诊病例 (17个eGIST,14个IAF) 的CT图像进行了回顾性分析.
- 评估损伤特征,包括位置,轮,边界,增强,损伤内含量 (,血管,脂肪,出血) 和尺寸参数 (LD,LD/SD比,体积).
- 使用费舍尔精确测试,学生t测试和ROC曲线进行统计分析,以确定显著的CT标准.
主要成果:
- 显著的CT区分因素包括非介质位置,不规则的轮,明确的边界,异质增强,内伤性亡/血管,缺乏脂肪,LD>9.6厘米,LD/SD比率>1.22,体积>603.3厘米 (P<0.05).
- 七个或更多标准的组合在区分eGIST和IAF方面实现了100%的特异性.
结论:
- 确定了十个不同的CT标准,以可靠地区分eGIST与IAF.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
