本文报道支气管肺癌CT扫描40例。并与常规X线照片和临床病理资料对照,论述CT扫描在支气管肺癌诊断中的作用。CT提供的胸部横断面图象,有利于发现重叠部位和普通X线难于发现的病灶,特别是被大量胸水,胸膜增厚、肺不张所掩盖的癌瘤病灶和位于脊柱旁的癌瘤病灶,从而补充了普通X线照片的不足,提高了对支气管肺癌的诊断准确率。 This article reported 40 cases of lung cancer CT scan. And compared with conventional radiographs and clinicopathological data, the role of CT scan in the diagnosis of bronchial carcinoma was discussed. CT provides a cross-sectional image of the chest, which facilitates the discovery of overlapping sites and difficult-to-find lesions on the ordinary X-ray, especially for cancerous lesions covered by massive pleural effusions, pleural thickening, atelectasis, and paraneoplastic lesions. This supplements the deficiency of normal X-ray photographs and improves the diagnostic accuracy of bronchogenic lung cancer.
