目的探讨64排螺旋CT在胃肠道间质瘤临床诊断中的应用价值,为今后的工作提供参考依据。方法将2013年3月~2014年3月期间我院收治的57例胃肠道间质瘤患者(均经手术病理证实)作为本组研究的观察对象,所有患者经64排螺旋CT检查,对病变的部位、大小、形态、边界以及增强扫描后肿瘤的强化特点进行回顾性分析。结果本组57例患者中,分布情况:胃部25例、小肠16例、结肠9例、肠系膜7例;病理结果 :恶性38例,良性16例,潜在恶性3例;影像特点:恶性肿瘤平均直径>5cm,呈类圆形或分叶样,边缘不清、密度不均匀、多伴有瘤体中心液化(坏死),增强扫描后不均匀强化、延迟扫描强化更明显;良性肿瘤平均直径<5cm,呈类圆形、边界清晰、密度较均匀、增强后多均匀强化;潜在恶性肿瘤密度较均匀。结论在胃肠道间质瘤的临床诊断中应用64排螺旋CT,可以清晰显示肿瘤的部位、大小、形态及内部结构,通过动态增强检查在胃肠道间质瘤的定位、定性诊断中有重要的指导价值。
Objective To explore the value of 64-slice spiral CT in the clinical diagnosis of gastrointestinal stromal tumors and provide reference for future work. Methods Fifty-seven patients with gastrointestinal stromal tumors (confirmed by surgery and pathology) admitted to our hospital from March 2013 to March 2014 were selected as the observation group. All patients were examined by 64-slice spiral CT, The location, size, shape, boundary of the lesion and enhancement of the tumor after enhanced scan were analyzed retrospectively. Results Among the 57 patients in this group, 25 were in the stomach, 16 in the small intestine, 9 in the colon and 7 in the mesentery. The pathological findings were malignant in 38, benign in 16, and potentially malignant in 3. Imaging features: Malignant tumors averaged Diameter> 5cm, were round or lobulated, unclear edge, uneven density, often accompanied by tumor center liquefaction (necrosis), enhanced after scanning uneven enhancement, delayed scan enhanced more obvious; benign tumor with an average diameter of < 5cm, was round, clear boundaries, more uniform density, enhanced multi-uniform enhanced; potential density of malignant tumors more evenly. Conclusion The application of 64-slice spiral CT in the clinical diagnosis of gastrointestinal stromal tumors can clearly show the location, size, shape and internal structure of the tumor. Through the dynamic enhancement of the localization of gastrointestinal stromal tumors, there are Important guide value.
