| 中文摘要: |
| 作者对手术病理证实的110例肺内孤立病灶的CT检查方法与诊断进行了分析研究, 结果表明：双窗位对病灶显示有一定的局限性, 采用肺窗位并作选择调节对病灶显示有独特的作用；病灶薄层扫描不仅能显示病灶的形态特征, 而且能揭示病灶所属支气管改变, 从而进一步提高孤立病灶的定性诊断水平。良恶性病灶的CT表现既各有特点, 又互有交叉：病灶>3cm;具有分叶、毛刺；密度不均者以恶性多见。若<3cm, 无分叶、边缘光滑、密度均匀者多见于良性。 |
| 英文摘要: |
| Computed tomography was used to examine 110 solitary pulmonary nodules.Each lesion was proved by surgery and pathology.Scanning methods and diagnosis were discussed in this article.Conclusions were drawn:double window was limited to observe lesions,whereas lung window was highly effective in showing the characteristics of lesions;In the assessment of pulmonary nodules thin section CT was effective not only in displaying the edge and internal characteristics of lesions,but also in demonstrating the involvement of bronchi;a lesion was apt to malignant if it exhibited:Larger than 3cm in diameter;Lobulation or spiculation;Inhomogenous attenuation.Benign lesions were mostly smaller than 3cm in size and exhibited smooth margin and homogeneous attenuation more frequently. |
