PurposeTo validate a CT-navigation system during percutaneous lung biopsy (PLB).MethodsFour 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.ResultsHysto-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.ConclusionsCT-navigation system allowed a good success in terms of diagnosis in small lesions and when a long DTP is required.
