To evaluate the potential role of three-dimensional (3D) computed tomography (CT) in assessment of pleural invasion by peripheral bronchogenic carcinoma.
Twenty-four-second helical CT scans were obtained during a single breath hold in 42 consecutive patients with peripheral bronchogenic carcinoma. Conventional two-dimensional (2D) images and 3D reconstruction images were reviewed independently by three blinded observers, who reached a decision by consensus. All patients underwent surgical resection of the tumor, and CT findings were correlated with the findings in pathologic specimens.
Twelve patients had visceral pleural invasion, five had parietal pleural invasion, and 25 had no evidence of pleural invasion. Visceral pleural invasion was identified on 2D CT images in two patients and on 3D reconstructions in 11. Parietal pleural invasion was identified on 2D CT images in two patients and on 3D reconstructions in three.
3D reconstruction imaging is superior to conventional 2D CT in assessment of pleural invasion by peripheral bronchogenic carcinoma.
评估三维（3D）计算机断层扫描（CT）在外周型支气管肺癌胸膜侵犯评估中的潜在作用。
对42例连续的外周型支气管肺癌患者在一次屏气期间进行24秒螺旋CT扫描。三位不知情的观察者独立查看传统二维（2D）图像和3D重建图像，并通过达成共识做出判断。所有患者均接受了肿瘤手术切除，CT检查结果与病理标本检查结果进行了对比。
12例患者存在脏层胸膜侵犯，5例存在壁层胸膜侵犯，25例无胸膜侵犯证据。2D CT图像上识别出2例脏层胸膜侵犯，3D重建图像上识别出11例。2D CT图像上识别出2例壁层胸膜侵犯，3D重建图像上识别出3例。
在评估外周型支气管肺癌的胸膜侵犯方面，3D重建成像优于传统2D CT。
