本文用CT扫描和X线胸片对140例肺癌病人作了诊断率的比较,CT对肺癌的诊断率为97.％,胸片为89.3％,并分析了15例肺癌在普通胸片上未能显示和显示不清楚的原因是被纵隔、横膈所掩蔽及其他病变影响等。本文又对140例中作了肺癌剖胸手术的28例病人作了胸片和CT扫描对局部淋巴结转移与肺部手术所见的比较,CT扫描对纵隔和肺内有淋巴结转移的显示率高于一般胸片,但CT也显示了4例假阳性。根据以上分析,CT扫描对肺癌的诊断有较大的优势,但也存在着局限性,我们认为如能提高X线胸片的摄片技术和进一步发挥断层摄影的质量,对肺癌的诊断率会有所提高,胸片在临床上有它重要的实用意义。
In this paper, CT scan and X-ray were used to compare the diagnostic rate of 140 lung cancer patients. The diagnostic rate of CT for lung cancer was 97.%, and the chest radiograph was 89.3%. 15 cases of lung cancer on the ordinary chest radiograph were analyzed. The reasons for the unclear display and display are due to mediastinal and diaphragmatic obstructions and other lesions. This paper also compared the chest radiographs and CT scans performed on 28 patients with lung cancer undergoing thoracotomy in 140 cases compared with those seen in lung surgery. The CT scan showed high rates of lymph node metastasis in the mediastinum and lung. On general chest radiographs, CT also showed 4 false positives. According to the above analysis, CT scan has a great advantage in the diagnosis of lung cancer, but there are also limitations. We believe that if we can improve the radiographic techniques of X-rays and further the quality of tomography, the diagnostic rate of lung cancer will be With some improvements, chest radiographs have important clinical significance.
