Advances in Methods of Localization of Pulmonary Nodules

近年来，随着计算机断层扫描(CT)在肺部疾病中筛查的广泛应用，再加上人们对定期检查认识的提高，从而有大量肺结节被检测出来，其中以磨玻璃样结节(Ground-glass nodule, GGN)最具有代表性。与实性结节相比，这些非实性结节，发生恶性肿瘤的可能性更高，在手术中通过触诊方法定位亚实性或磨玻璃影结节特别困难，因此如何准确定位成为完整切除此类结节的重点。本文总结了目前国内外对肺结节定位的研究进展，并分析其应用场景及优缺点。In recent years, with the widespread application of computed tomography (CT) in the screening of lung diseases, coupled with an increased awareness of the importance of regular check-ups, a significant number of pulmonary nodules have been detected. Among these, ground-glass nodules (GGNs) are the most representative. Compared to solid nodules, these non-solid nodules have a higher likelihood of being malignant. It is particularly challenging to locate sub-solid or ground-glass opacity nodules during surgery using palpation methods, making accurate localization crucial for the complete resection of such nodules. This article summarizes the current research progress in the localization of pulmonary nodules both domestically and internationally, and analyzes their application scenarios, advantages, and disadvantages.
