目的：提高原发性气管癌的影像学诊断水平。方法：进行８例原发性气管癌的Ｘ线、ＣＴ、ＭＲＩ检查与临床病理对照分析。结果：８例影像学显示气管壁广基底菜花状或乳头状肿块影致管腔狭窄，肿块大小２～４５ｃｍ，１例伴纵膈淋巴结肿大转移。病理诊断：气管鳞癌４例，腺样囊性癌４例。结论：ＭＲＩ多体位进行气管癌检查，在显示气管癌的形态、大小、气管壁浸润、纵膈淋巴结有无转移等信息优于Ｘ线和ＣＴ，有助于临床治疗方法选择及预后判断
Objective: To improve the imaging diagnosis of primary tracheal carcinoma. Methods: 8 cases of primary tracheal carcinoma by X-ray, CT, MRI examination and clinicopathological analysis. Results: 8 cases of imaging showed that the tracheal wall cauliflower or papillary mass led to luminal stenosis, the size of the tumor 2 ~ 4 5cm, 1 with enlarged mediastinal lymph node metastasis. Pathological diagnosis: squamous cell carcinoma in 4 cases, adenoid cystic carcinoma in 4 cases. Conclusion: MRI multi-position tracheal cancer examination, in the display of tracheal cancer morphology, size, invasion of the tracheal wall, mediastinal lymph node metastasis and other information is superior to X-ray and CT, contribute to the choice of clinical treatment and prognosis
