The biobsy procedure done at the radiology department and the cores are examined by the pathology department, the patient lie prone, supine or in lateral decubitus according to the location of the lesion. A thoracic CT scan was performed first to evaluate the needle pathway and distance from the puncture site to the lesion. The needle pathway was selected to avoid bone, visible vessels, bullae, and fissures. The puncture site was chosen by the CT gantry laser lights and landmarks using a homemade radiopaque grid on the patient's skin. Local anaesthesia was induced with 5 mL of 2% lidocaine. An 18-G coaxial needle was used to puncture the lung, and a repeat CT scan was performed to evaluate the site of the needle. When the needle tip reached the lesion, the specimen was obtained by pressing the trigger of the needle. The specimen was reviewed by the pathologist.The specimen was placed in 10% formaldehyde for pathological examination.
