目的探讨X线与CT诊断的影像学表现对周围型小肺癌早期诊断率的临床意义。方法将89例周围型小肺癌患者分别行X线片检查和螺旋CT薄层增强扫描,并分析所显现的影像学特征。结果 CT检查阳性率以边缘不规分叶征67例(51.69%)最多,显著高于X线片检查的46例(75.28%),两者比较,差异有统计学意义(P<0.05)。CT增强扫描对周围型小肺癌的诊断优于X线片检查。结论 CT薄层增强扫描可提高周围型小肺癌的早期诊断率。
Objective To investigate the clinical significance of imaging findings of X-ray and CT in early diagnosis of peripheral small lung cancer. Methods Eighty-nine patients with peripheral small lung cancer underwent radiography and spiral CT thin-layer contrast-enhanced scanning. The imaging features were analyzed. Results The positive rate of CT examination was 67 cases (51.69%) with marginal irregular lobulation, which was significantly higher than that of 46 cases (75.28%) with X-ray examination. The difference was statistically significant (P <0.05). CT enhanced scan on peripheral small lung cancer diagnosis is superior to X-ray examination. Conclusion CT thin layer enhanced scan can improve the early diagnosis of peripheral small lung cancer.
