CT was used for central intraparenchymal lung lesions (<i>n</i> = 11); US was used for mediastinal (<i>n</i> = 8), pleural (<i>n</i> = 9), and peripheral lung lesions (<i>n</i> = 12). Pneumothorax occurred in 18.2% (2/11) of CT-guided cases and 6.9% (2/29) of US-guided cases. One chest tube was required (3.4%). Pulmonary hemorrhage occurred in one CT-guided case (9.1%). There was no statistically significant difference in complication rates between the CT-guided and US-guided biopsy groups (<i>p</i> = 0.300).</p><p><strong>Conclusions: </strong>Image-guided transthoracic CNB is a safe and reliable diagnostic technique for thoracic lesions in pediatric patients, offering high diagnostic accuracy with low complication rates.</p>","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"91 ","pages":"e343-e350"},"PeriodicalIF":0.0,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13551576/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148914987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
