ABSTRACT
Objective To observe the clinical value of cone-beam computed tomography (CBCT) combined with iGuide system in percutaneous transthoracic needle biopsy (PTNB) of pulmonary lesions.Methods A total of 30 patients with solitary lung lesion underwent PTNB procedures were enrolled.The needle path was planned with iGuide system and 3D CT-like MPR images after CBCT.A coaxial system with 18-gauge cutting needle was used for biopsy.Procedure related data,complications and radiation exposure of patients were recorded.Results Among 30 patients,malignant lesions were found in 24,and benign lesions were in 6 patients.On PTNB,28 patients were correctly diagnosed,1 case was with insufficient samples but obtained correct pathologic result with second biopsy,1 case was false-negative finding.The diagnostic accuracy,sensitivity,specificity,positive predictive value and negative predictive value of PTNB in diagnosis of lung diseases was 96.67% (29/30),96.00% (24/25),100% (5/5),100% (24/24) and 83.33% (5/6),respectively.The mean procedure time was (13.03+3.61)min,and exposure dose was (7.95+4.57)mSv.After PTNB procedures,pneumothorax and hemoptysis occurred in 6 (6/30,20.00%) and 3 (3/30,10.00%) patients,respectively.Conclusion CBCT combined with iGuide system for guiding PTNB is accurate and safe with reasonable radiation exposure.
