Background: Increasing success rate and reducing complications are important for computed tomography (CT)-guided percutaneous core needle biopsy (PCNB). Objectives: To assess the influence of needle angle and lesion depth on procedural success and complications of CT-guided PCNB for intrapulmonary lesions, performed by a single radiologist. Results: The overall success rate was 93.1% (642/689). Procedural success showed no statistically significant association with both needle angle (P = 0.568) and lesion depth (P = 0.144). The overall complication rate was 17.9% (123/689) with 15.7% for minor complications and 2.2% for major complications. The needle angle had no association with complications (P = 0.101). Presence and severity of complications showed a direct relationship with lesion depth (P < 0.01). In fact, more severe complications occurred in deeper located lesions. Conclusion: Needle angle had no effect on both procedural success and complications. Also, there was no significant correlation between lesion depth and procedural success. However, lesion depth was closely correlated with the incidence and severity of complications after PCNB.
