Objectives:
Computed tomography-guided core needle biopsy has an important role in the accurate histopathological diagnosis of lung masses. The present study aims to share our results of computed tomography-guided percutaneous core needle biopsy of lung masses.
Methods:
A total of 117 patients had computed tomography-guided percutaneous core needle biopsy for lung masses between January 2017-September 2019 in our institution. In this study, these patients' post-procedural complications, diagnostic-yield-rates and radiological-histopathological correlations were evaluated retrospectively.
Results:
Complications occurred in 23 (20%) patients (20 (17%) of pneumothorax; 3 (3%) of hemorrhage). Chest-tube-drainage was needed in five (4%) of all patients. No significant difference was found between complication rates and patient gender/age, tumor volume/localization or needle-path-length (p>0.05). In 77 of the 85 (91%) primary-lung-cancer-cases radiological and pathological diagnostic results were correlated.
Conclusion:
Computed tomography-guided core needle biopsy has a high diagnostic yield rate with acceptable complication rates in the diagnosis of lung masses.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
