Invasive modalities for the diagnosis of peripheral lung nodules

Area of Science:

• Pulmonology
• Diagnostic Imaging
• Interventional Pulmonology

Background:

• Lung nodules are frequently detected via incidental findings and lung cancer screening CT scans.
• Accurate and prompt diagnosis of potentially malignant lung nodules is essential.

Purpose of the Study:

• To review invasive diagnostic modalities for lung nodules.
• To evaluate emerging technologies like cone-beam CT and robotic bronchoscopy.

Main Methods:

• Literature review of key studies obtained from PubMed searches.
• Discussion of current data supporting the use of diagnostic technologies.

Main Results:

• CT-guided biopsy offers high yield but carries pneumothorax risk.
• Standard bronchoscopy has a better safety profile but lower diagnostic yield.
• Emerging technologies demonstrate improved diagnostic yield compared to existing methods.

Conclusions:

• The optimal approach for lung nodule diagnosis is evolving.
• Cone-beam CT and robotic bronchoscopy represent advancements in nodule sampling.
• Further data is needed to fully establish the role of novel technologies.
