目的:利用螺旋CT动态增强扫描,对中央型肺癌纵隔大血管侵犯程度的评价,以探讨其应用价值。方法:对7例中央型肺癌的患者采用双相注射法的螺旋CT动态增强扫描。结果:左肺动脉受侵犯3例,属Ⅱ级;右肺动脉受侵犯3例,属Ⅲ级;右下肺动脉受侵犯1例,为Ⅳ级。结论:螺旋CT动态增强扫描对中央型肺癌术前的肿瘤分期、手术方案的制定上有指导意义。
OBJECTIVE: To evaluate the extent of invasion of mediastinal large vessels in central lung cancer by dynamic contrast-enhanced spiral computed tomography (CT) to explore its application value. Methods: Seven patients with central lung cancer underwent two-phase injection of spiral CT dynamic contrast-enhanced scan. Results: 3 cases of left pulmonary artery involvement were grade Ⅱ, 3 cases of right pulmonary artery involvement, grade Ⅲ, and 1 case of inferior right pulmonary artery was grade Ⅳ. Conclusion: Spiral CT dynamic contrast-enhanced scanning is helpful for the preoperative tumor staging and surgical planning of central lung cancer.
