本文复习了侧后倾斜位断层摄影的基本操作方法并提出初步改进意见,就150例胸部平片指征选择拍摄的断层像进行了观察分析。本组病例中肺癌133例、炎症17例,平片诊断47例(占31％)、断层诊断139例(占93％),误诊11例(占3％),通过观察分析,重电说明本法摄影对支气管病变的诊断价值,特别是对中心型肺癌的诊断和鉴别诊断以及对肺门淋巴结增大的判定价值应给以肯定。此法对病人无痛苦,检查操作并不困难,凡有断层设施的单位都可采用。
This paper reviews the basic operation methods of posterior oblique oblique tomography and proposes preliminary improvement suggestions. The 150 cases of chest radiographs selected for the imaging of the tomographic images were observed and analyzed. In this group of patients, there were 133 cases of lung cancer, 17 cases of inflammation, 47 cases of plain film diagnosis (31%), 139 cases of diagnosis (93%), and 11 cases (3%) misdiagnosis. The diagnostic value of French photography for bronchial lesions, especially for the diagnosis and differential diagnosis of central lung cancer and the value of the determination of hilar lymph node enlargement, should be affirmed. This method is painless to the patient, and the inspection operation is not difficult. All units with fault facilities can be used.
