目的评估螺旋CT多层平面重建(MPR)在食管癌术前分期中的应用价值。方法选择86例食管癌患者,回顾性分析螺旋CT影像学资料,并与病理资料进行对照,分析螺旋CT对食管癌术前分期的判断准确性,观察项目包括食管癌病变部位、肿瘤对周围组织、器官的侵犯以及Moss改良分期。结果螺旋CT能够显示病灶的位置、范围,管壁及管腔的变化以及周围脂肪的异常改变。本组螺旋CT的食管癌术前分期诊断准确性为80.2%(69/86),对食管癌术前外侵的诊断准确性为87.2%(75/86),对食管癌术前淋巴结转移的诊断准确性为83.7%(72/86)。结论螺旋CT在食管癌术前分期中具有重要的临床应用价值,能够判断病灶的位置、范围、管壁及管腔的变化以及周围脂肪的异常改变等,为临床诊治提供可靠的参考依据。
Objective To evaluate the value of spiral CT multi-slice planar reconstruction (MPR) in the preoperative staging of esophageal cancer. Methods Eighty-six patients with esophageal cancer were selected. The data of spiral CT were retrospectively analyzed and compared with the pathological data to analyze the accuracy of spiral CT in the preoperative staging of esophageal cancer. The observation items included esophageal cancer lesions, , Organ invasion and Moss improved staging. Results Spiral CT can show the location of the lesions, the extent of the wall and the lumen of the changes and changes in the surrounding fat abnormalities. The diagnostic accuracy of preoperative staging of esophageal cancer was 80.2% (69/86) in this group, and 87.2% (75/86) in diagnosing preoperative esophageal cancer. The accuracy of preoperative lymph node metastasis of esophageal cancer The diagnostic accuracy was 83.7% (72/86). Conclusion Spiral CT has important clinical value in the preoperative staging of esophageal cancer, which can determine the location, range, changes of the wall and lumen and the abnormal changes of the surrounding fat. It can provide a reliable reference for clinical diagnosis and treatment.
