PURPOSE
To validate a CT-navigation system during percutaneous lung biopsy (PLB).
METHODS
Four hundred-ninety-six patients underwent low-dose CT-guided PLB. Lesion diameter (LD), procedural time (PT), histologic validity, lesion distance from pleural surface (DPS), needle distance travelled during procedure (DTP), complications and radiation exposure were recorded.
RESULTS
Hysto-patological diagnosis was obtained in 96.2% cases. Mean PT, DPS, DTP, LD were respectively 29.5min, 12.4mm, 17.9mm, 20.7mm. In cases of major complications (4.6%), higher values of DTP were measured.
CONCLUSIONS
CT-navigation system allowed a good success in terms of diagnosis in small lesions and when a long DTP is required.
目的
在经皮肺活检（PLB）过程中验证一种CT导航系统。
方法
496例患者接受了低剂量CT引导下的PLB。记录病变直径（LD）、操作时间（PT）、组织学有效性、病变距胸膜表面的距离（DPS）、操作过程中针行进的距离（DTP）、并发症和辐射暴露情况。
结果
96.2%的病例获得了组织病理学诊断。平均PT、DPS、DTP、LD分别为29.5分钟、12.4毫米、17.9毫米、20.7毫米。在主要并发症病例（4.6%）中，测量到较高的DTP值。
结论
CT导航系统在小病变诊断以及需要长DTP时诊断成功率较高。
