【摘要】 目的:建立中央型肺癌125I粒子植入治疗术前MRI病变分型模式并探讨其临床价值。方法:44例中央型肺癌患者行胸部MRI检查。根据中央型肺癌的信号特征、气道浸润、纵隔蔓延以及心脏大血管侵犯等异常MRI表现,结合术前粒子植入靶区的定位及术式选择等需要,将中央型肺癌术前MRI表现分成5型。结果:I型3例,为肺门孤立肿块,其中Ⅰa型2例,Ⅰb型1例;Ⅱ型7例,均发生阻塞性肺不张;Ⅲ型18例,均出现纵隔淋巴结转移;Ⅳ型7例,均发生心脏及大血管受累;Ⅴ型9例,均发生严重气道浸润。结论:中央型肺癌125I粒子植入术前MRI病变分型对术前靶区定位及术式选择等具有重要临床价值,是TNM分期的重要补充。更多还原

【Abstract】 Objective:To establish MRI evaluation mode in the therapy with interstitial implantation of (125)~I seed for central bronchial carcinoma before operation,and its clinical value thereof.Methods:Forty-four cases of central bronchial carcinoma were imaged by MRI.Patients were randomly divided into 5 types according to the mass signal,mass complications,bronchus abnormal features,metabasis of the hilar and mediastinal lymph nodes,mediastinal invasion,cardiac and vascular invasion,as well as chest wall involved.Results:There were 3 cases in gradeⅠ(Ⅰa 2,Ⅰb 1),7 cases in gradeⅡ,18 cases in grade Ⅲ,7 cases in grade Ⅳand 9 cases in gradeⅤ.Conclusion:Preoperative grouping of the therapy with interstitial implantation of (125)~I seed for central bronchial carcinoma is very valuable for the orientation of the mass target,localization of the puncture,confirmation of the modus operandi,as well as making sure of the risk in the operation.更多还原
