Endoscopic Ultrasound-Guided Fine Needle Aspiration of Mediastinal Lymph Node in Patients With Suspected Lung Cancer After Positron Emission Tomography and Computed Tomography Scans

EUS-FNA is a safe, accurate, and minimally invasive technique that improves the staging of patients with NSCLC. It is more accurate and has a higher predictive value than either the PET scan or CT scan for posterior mediastinal lymph nodes.
