Computed tomography fluoroscopy-guided percutaneous biopsy of pulmonary nodules ≤ 10 mm: retrospective analysis of procedures performed during the COVID-19 pandemic

Abstract Objective: To evaluate the diagnostic performance of computed tomography (CT) fluoroscopy-guided percutaneous transthoracic needle biopsy (PTNB) in pulmonary nodules ≤ 10 mm during the coronavirus disease 2019 pandemic. Materials and Methods: Between January 1, 2020 and April 30, 2022, a total of 359 CT fluoroscopy-guided PTNBs were performed at an interventional radiology center. Lung lesions measured between 2 mm and 108 mm. Of the 359 PTNBs, 27 (7.5%) were performed with an 18G core needle on nodules ≤ 10 mm in diameter. Results: Among the 27 biopsies performed on nodules ≤ 10 mm, the lesions measured

摘要 目的：评估2019冠状病毒病疫情期间，计算机断层扫描（CT）透视引导下经皮经胸针穿刺活检（PTNB）对直径≤10mm肺结节的诊断效能。材料与方法：2020年1月1日至2022年4月30日期间，某介入放射学中心共完成359例CT透视引导下经皮经胸针穿刺活检操作，纳入研究的肺部病灶直径范围为2mm至108mm。在上述359例操作中，有27例（占比7.5%）为使用18G核心针对直径≤10mm的肺结节实施的穿刺活检。结果：针对直径≤10mm肺结节完成的27例活检中，病灶直径为
