:对比研究普通CT和高分辨力CT在肺癌肺转移性结节的诊断价值 ,39例肺癌肺转移性结节采用普通CT和HRCT扫描。评价普通CT和HRCT扫描对肺癌肺转移性结节的显示 ,分别记录①原发肿瘤的部位 ;②结节的分布 ;③结节的大小 ;④结节的边缘形态 ;⑤结节的内部密度。HRCT扫描对肺癌肺转移性结节的显示明显高于普通CT ,HRCT清楚显示结节边缘菱角征和内部低密度环征。肺部普通CT扫描加HRCT扫描对肺癌肺转移性结节的诊断有明显的价值。
: To compare the diagnostic value of common CT and high-resolution CT in the lung metastatic nodules of lung cancer, and 39 cases of lung cancer lung metastatic nodules using ordinary CT and HRCT scans. Evaluation of common CT and HRCT scan of lung cancer lung nodules were recorded, were recorded ① primary tumor site; ② nodules distribution; ③ nodule size; ④ nodules edge morphology; ⑤ nodules of the internal density . HRCT scan of lung metastasis of lung nodules showed significantly higher than the normal CT, HRCT clearly shows nodular edge of the water chestnut symptoms and internal low-density ring sign. Common lung CT scan and HRCT scan lung metastases of lung nodules have obvious value.
