[Research Progress on Localization of Pulmonary Nodules]

Area of Science:

• Thoracic Surgery
• Medical Imaging
• Oncology

Background:

• Improved low-dose computed tomography (LDCT) enhances pulmonary nodule detection, increasing the need for precise localization.
• Pulmonary nodule size correlates with malignancy risk, making accurate localization critical for effective treatment.
• Video-assisted thoracoscopic surgery (VATS) is the preferred method for pulmonary nodule resection, demanding precise pre-operative localization.

Approach:

• This review synthesizes recent research on pulmonary nodule localization techniques.
• It evaluates the strengths and limitations of various methods, including CT-guided, bronchoscope-guided, ultrasound-guided, augmented reality (AR), and 3D print-assisted positioning.
• The analysis aims to inform clinical practice and direct future research.

Key Points:

• Accurate localization is a persistent challenge in thoracic surgery for pulmonary nodules.
• Current methods offer diverse approaches with varying degrees of precision and invasiveness.
• Augmented reality and 3D printing represent emerging technologies in nodule localization.

Conclusions:

• Understanding the nuances of each localization method is essential for optimizing VATS outcomes.
• Further research is needed to refine existing techniques and develop novel approaches for pulmonary nodule localization.
• This review provides a comprehensive overview to guide clinicians and researchers in this critical area of thoracic surgery.
