方法：9例志愿者行主动脉弓同层动态增强扫描，利用获得的主动脉弓时间-密度曲线（TDC），寻求触发技术的理论阈值。
Methods:Dynamic CT scan was performed in 9 volunteers, measuring the CT value of the same plane of aortic arch and the theoretical threshold was obtained by the time density curve(TDC).
混合瘤时间密度曲线呈缓升缓降型；
Time density dynamic perfusion curve of the tumor is slow rising and slow descending.
结论结核瘤动态增强CT扫描在强化值、时间一密度曲线及强化形态均有一定特征，可与周围型肺癌及炎性肿块相鉴别。
Conclusion: Tuberculoma can be differentiated from peripheral pulmonary carcinoma or inflammatory mass by the characteristic of maximum enhanced ct value, enhanced pattern and time-attenuation curves.
