Transbronchial biopsy with real-time X-ray imaging — improving diagnostic accuracy and reducing complication risk during bronchoscopic tissue sampling.
A transbronchial biopsy (TBBX) collects tissue samples from within the lung during bronchoscopy. Fluoroscopy — continuous real-time X-ray imaging — is used simultaneously to guide instrument placement throughout the procedure.
This combination significantly enhances diagnostic accuracy by confirming biopsy instrument position before sampling, while also lowering the incidence of complications such as pneumothorax (collapsed lung).
TBBX with fluoroscopic guidance is commonly used to diagnose lung infections, tumors, and inflammatory conditions such as sarcoidosis.
