The feasibility of three-dimensionally printed navigational template-guided percutaneous transthoracic fine-needle aspiration was validated by a phase I study. To further investigate the non-inferiority of navigational template-guided lung biopsy to conventional CT-guided modality in terms of diagnostic yield, this prospective, randomized, controlled, noninferiority trial was conducted.
This is a prospective, randomized, controlled study to evaluate the diagnostic yield and safety of three-dimensionally printed navigational template in percutaneous transthoracic lung biopsy.
