RESUMO

Objective: This study sought to establish the diagnostic utility of performing a second biopsy using an magnetic resonance (MR)-guided percutaneous transthoracic needle biopsy (PTNB) approach in patients with suspicious malignant lung lesions that had already undergone an initial negative computed tomography (CT)-guided biopsy. Materials and Methods: This study evaluated 31 patients with suspicious lung lesions (18 males, 13 females; mean age: 62.1 ± 11.3 years) that had previously undergone CT-guided PTNB with negative pathological findings January 2015-November 2020. A final histopathological diagnosis was made based on resected lung lesion specimens or, when resection was not conducted, on clinical diagnosis following a ≥6-month follow-up. The diagnostic accuracy of MR-guided secondary lung biopsy was determined by comparing the lung biopsy results for each patient to their final diagnosis. Results: 1.0T open MR-guided secondary lung biopsy was performed for 31 lesions (20 central, 11 peripheral; mean size, 5.3 ± 2.0 cm). The pathological results revealed 20/31 (64.5%) lesions to be malignant (14 adenocarcinoma, 4 squamous cell carcinoma, and 2 small-cell lung cancer) as detected by 1.0T open MR-guided PTNB and confirmed by surgical pathology and clinical follow-up. There were three instances of biopsy-induced complications including hemorrhage in 6.5% of the patients (2/31) and pneumothorax in 3.2% of the patients (1/31). No patients experienced severe complications. Conclusion: For individuals with clinically suspicious lung lesions that initially received negative CT-guided PTNB findings, 1.0T open MR-guided secondary lung biopsy is a safe and effective secondary diagnostic approach.
