摘要
目的采用电子束CT(EBCT)双期增强扫描,对肺门区肺癌进行术前前瞻性评价,探讨其指导手术的临床价值。方法对40例拟诊为肺门区肺癌的患者行EBCT双期增强扫描后分析肿物与气管、主支气管、及肺门、纵隔大血管的关系,与手术结果进行对照。结果手术病理证实肺门区肺癌38例,术前根据EBCT扫描将病变分为:可切除组28例,与手术结果符合25例,符合率89.3%;不可切除组10例,与手术探查结果符合8例,符合率80%。EBCT双期扫描评价肺门区肺癌与肺门、纵隔结构关系的敏感度为92.6%(25/27),特异度为72.7%(8/11),准确度86.8%(33/38)。结论EBCT双期扫描对肺门区肺癌的术前评价是准确而可行的,具有较高的临床价值。
Objective To explore the clinical value of duralphase enhanced electronic beamcom puted tomography (EBCT)scans in resectability evaluation of lung cancer located in hilar region.Methods Dual phase enhanced EBCT scans were available for 40cases that were initially diagnosed as “carcinoma of lung”in hilar region.T he relations between masses and trachea,bronchi,hilar and mediastinal great vessels were analyzed and com pared with operation.Results 38 cases in our series confirm ed by operation and pathological exam ination were divided two groups: respectable (28cases)and non-resectable (10cases)groups.25cases in the former group were consistent with operation, accounting for 89.3% , and 8 cases, in the latter group,accounting for 80% . The sensitivity, specificity and accuracy of dural -phase enhanced EBCT scan evaluating the relations between masses and hilar and mediastinal structure were as follows:92.6% ,72.7% and 86.8% .C onclusion D ural-phase enhanced EBCT scans can provide precise and feasible pre -operative evaluation of lung cancer in hilar region.
