Radial Probe EBUS
Radial Probe Endobronchial Ultrasound (Radial EBUS)
Radial Probe Endobronchial Ultrasound (Radial EBUS) is a minimally invasive bronchoscopic technique used to locate and diagnose peripheral pulmonary nodules (PPNs) and small lung masses deep inside the lungs
How It Works
360-Degree Imaging: A miniature rotating ultrasound transducer is passed through the working channel of a flexible bronchoscope (often housed inside a protective guide sheath).
Real-Time Localization: It produces a live 360-degree radial image of the airway wall and surrounding lung tissue, letting the physician distinguish normal air-filled lung parenchyma from solid tumors or lesions.
Guided Biopsy: Once the ultrasound confirms the probe is inside or adjacent to the lesion, the ultrasound probe is removed while leaving the guide sheath in place. Forceps, a cytology brush, or a needle are then threaded through the sheath to collect tissue samples
Key Benefits
Deep Access: Reaches peripheral lung regions that standard convex probe EBUS cannot access.
High Accuracy: Improves diagnostic yield for small peripheral nodules (especially those under 2 cm).
Lower Risk Profile: Offers a safer alternative to CT-guided transthoracic needle aspiration (TTNA), significantly reducing the risk of complications like pneumothorax (collapsed lung).
