鼻咽癌放疗后局部复发与纤维化的同层动态CT增强研究

Single-location dynamic enhancement CT in recurrent nasopharyngeal carcinoma and radiofibrosis

目的 :探讨螺旋CT动态增强扫描在鉴别鼻咽癌放疗后局部复发与纤维化中的应用价值。方法 :选择鼻咽癌放疗后复发病人 35例 ,纤维化者 4 0例 ,行同层动态CT增强研究 ,绘制其时间 密度曲线。结果 :鼻咽癌放疗后复发与纤维化的动态增强特点明显不同。结论 :螺旋CT动态增强扫描有助于鉴别鼻咽癌放疗后复发与纤维化。

Objective:To investigate the value of single-location dynamic enhancement CT in differentiating recurrent nasopharyngeal carcinoma from radiofibrosis.Methods:Dynamic enhancement CT in patients with recurrent nasopharyngeal carcinoma and radiofibrosis were analyzed and the time-attenuation curves were created.Results:The characteristics of dynamic enhancement CT in recurrent nasopharyngeal carcinoma was significantly different from that in radiofibrosis.Conclusion:Single-location dynamic enhancement CT is helpful in differentiating recurrent nasopharyngeal carcinoma from radiofibrosis.
