Our study investigated the relationships between tumors and surrounding structures, particularly vessels and bronchi within lesions in the periphery of the lung. We performed axial multiplanar reconstruction CT (AMPR-CT) with a Toshiba TCT-900S scanner, as well as conventional CT (Conv. CT) and CR tomography (CR tomo.). We examined 19 patients with pulmonary lesions who later underwent surgical resection (12 with lung cancer, 1 with metastatic tumor, 1 with hamartoma, 2 with tuberculoma, and 3 with pulmonary granuloma) of a total of 43 patients with small nodular lesions less than 3 cm in diameter. AMPR-CT, Conv. CT, and CR tomo. were compared against resected specimens. The accuracy of each modality to detect involvement of bronchus, the pulmonary artery, and vein was AMPR-CT 50%:93%:91%, Conv. CT 47%:76%:55% and CR tomo. 37%:55%:42%, respectively. AMPR-CT was judged superior to both Conv. CT and CR tomo. In conclusions: 1) That AMPR-CT permits easier visualization of vessels and bronchi, and 2) That AMPR-CT is more effective than Conv. CT examinations in the morphological assessment of small nodular lesions. Thus, AMPR-CT is a useful new approach to the diagnosis of lesions in the lung.
我们的研究调查了肿瘤与周围结构之间的关系，特别是肺外周病变内的血管和支气管。我们使用东芝TCT - 900S扫描仪进行了轴向多平面重建CT（AMPR - CT），以及传统CT（Conv. CT）和CR断层扫描（CR tomo.）。我们检查了19例肺部病变患者，这些患者后来接受了手术切除（12例肺癌，1例转移瘤，1例错构瘤，2例结核瘤，3例肺肉芽肿），总共43例直径小于3 cm的小结节病变患者。将AMPR - CT、Conv. CT和CR tomo.与切除标本进行比较。每种方法检测支气管、肺动脉和静脉受累的准确率分别为AMPR - CT 50%:93%:91%，Conv. CT 47%:76%:55%，CR tomo. 37%:55%:42%。AMPR - CT被判定优于Conv. CT和CR tomo.。结论如下：1）AMPR - CT能更轻松地显示血管和支气管；2）在小结节病变的形态学评估中，AMPR - CT比Conv. CT检查更有效。因此，AMPR - CT是一种诊断肺部病变的有用新方法。
