Objective: To prospectively evaluate the feasibility, accuracy, and safety of multiparameter MRI-guided percutaneous biopsy using a 1T open MRI scanner for evaluating suspicious centrally located lung lesions with associated post-obstructive atelectasis. Materials and Methods: In this single-center study, MRI-guided percutaneous coaxial cutting biopsy was performed for 107 suspicious central lung lesions with associated post-obstructive atelectasis in 107 patients between July 2015 and December 2020. A fast T2-weighted imaging (T2WI)-turbo spin echo (TSE) sequence and an enhanced fast T1-weighted imaging (T1WI)-TSE sequence were used to identify, localize, and biopsy lung lesions, and diffusion-weighted imaging (DWI) was used as a supplementary sequence for identifying the lesion location. The final diagnosis was confirmed by surgical histopathology or clinical follow-up for a minimum of 24 months. The sensitivity, specificity, and accuracy for diagnosing lung malignancies were calculated, and the complications were recorded for each case. Results: Using multiparameter MRI, central lung lesions could be clearly distinguished from post-obstructive atelectasis in 96 patients (89.7%). The sensitivity, specificity, and accuracy of MRI-guided percutaneous biopsy for diagnosing lung malignancy was 97.0% (98/101), 100% (6/6), and 97.2% (104/107), respectively. Self-limited hemoptysis occurred in three patients. Pneumothorax occurred in five patients, of which none required pleural drainage. No serious procedure-related complications were observed. Conclusion: As a technology that does not involve ionizing radiation, multiparameter MRI-guided percutaneous coaxial cutting biopsy is a safe and accurate diagnostic technique for evaluating centrally located lung lesions associated with post-obstructive atelectasis.
