Low-dose computed tomography (LDCT) screening has increased the detection rate for small pulmonary nodules with ground-glass opacity (GGO) in the peripheral lung parenchyma. Minimally invasive thoracoscopic surgery for these lung nodules is challenging for thoracic surgeons, and image-guided preoperative localization is mandatory for their successful resection. Image-guided localization methods primarily include two imaging tools: computed tomography (CT) and bronchoscopy. These different methods may use different localized materials, including hookwires, dyes, microcoils, fiducial markers, contrast media, and radiotracers. Ultrasonography and near-infrared imaging are also used for intraoperative localization of lung lesions. In this article, we review different localization techniques and discuss their indications and limitations.
低剂量计算机断层扫描（LDCT）筛查提高了外周肺实质内磨玻璃密度影（GGO）小肺结节的检出率。对于这些肺结节，微创胸腔镜手术对胸外科医生来说具有挑战性，术前影像引导定位对于成功切除结节至关重要。影像引导定位方法主要包括两种成像工具：计算机断层扫描（CT）和支气管镜检查。这些不同的方法可能使用不同的定位材料，包括钩丝、染料、微线圈、基准标记物、造影剂和放射性示踪剂。超声检查和近红外成像也用于肺病变的术中定位。在本文中，我们回顾了不同的定位技术，并讨论了它们的适应症和局限性。
