肺癌肺转移的高分辨力CT评价

High-resolution CT in the assessment of lung carcinoma with pulmonary metastasis

: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。

This study was to compare the diagnostic evaluation of high-resolution CT with conventional CT for pulmonary metastatic nodules of lung carcinoma.39 cases of pulmonary metastatic nodules of lung carcinoma were obtained with convertional CT and high-resolution CT.To evaluate the sigificance of high-resolution CT and conventional CT to the pulmonary metastatic nodules of lung carcinoma.The characteristic CT features are analyzied this study ①location of the primary turmor ②distribution of nodules ③small and large of nodules ④perifocal features of nodules ⑤density of nodules.HRCT is more marked on the pulmonary matastatic nodules of lung carcinoma than conventional CT.HRCT showed clearly internal low density and perifocal indentation sign for metastatic nodules.It has a important diagnosis value to combine using HRCT and conventional CT scans for pulmonary metastatic nodules of lung carcinoma.
