胸部CT对肺癌早期诊断和鉴别诊断是胸片和体层有价值补充检查方法。在普通CT基础上补充高分辨CT扫描和螺旋CT扫描有时可以提供对于诊断有价值信息。
Abstract Thorcic CT is a valuable examining method in early diagnosis and differential diagnosis of bronchial car cinoma. It is a useful complement to chest radiogram and oonventionl tomogram. High resolution CT and spiral CT on the basis of routine CT may provide useful information to diagnosis.In the diagnosis of early peripheral bronchial carcinoma, besides solitary nodule in lungs, lobulation and spiculation of nodular margin, bronchogram and excavation of pleura are also valuable. Contrast CT will contribribute to differentiate benign from malignant tumor sometimes.The value of CT in diagnosing central bronchial carcinoma lies in demonstrating stenosis and obstruction of bronchus and thickening of bronchial wall. Thin section spiral CT is conducive to observing segmental bronchus.In addition, thoracic CT examination conduces to staging bronchial carcinoma.
