| 摘要: |
| 探讨CT导引肺内小结节（≤2cm）穿刺活检的临床应用价值。［方法］31例，在CT导引下应用自动切割式活检针取材。所有病例均同时行组织学和细胞学检查。［结果］穿刺取材成功率为90.3%（28/31），恶性结节组织学准确率为84.2%（16/19），细胞学准确率为89.5%（17/19），二者结合准确率89.5%（17/19）。良性结节分别为66.7%(6/9)和77.8%(7/9),二者结合准确率88.9%（8/9）。气胸发生率为10/31（32.6%）。［结论］CT导引肺内小结节穿刺活检安全可行 |

| Abstract: |
| To explore the clinical value of CT-guided needle biopsy of the small intrapulmonary nodules(less than 2 cm in diameter). ［Methods］ CT-guided percutaneous biopsy were performed in 31 cases with automated cutting needle. Bioptic samples were examined in histology and cytology simultaneously. ［Results］The accuracy of puncture was 90.3 % (28/3); Diagnostic accuracy of malignant tumor was 84.2 % (16/19) in cytologic study and 89.5 %(17/19) in histologic examination. The overall diagnostic accuracy was 89.5 % (17/19). Diagnostic accuracy of benign nodules was 66.7 % (6/9) in cytologic study and 77.8 %(7/9) in histologic examination. The overall diagnostic accuracy was 88.9 % (8/9). The incidence of pne umothorax was 32.6 % (10/31). ［Conclusion］ CT-guided needle biopsy of the small intrapulmonary nodules is a safe and effective procedure. |
