Description of intervention(s) / exposure
Treatment: Surgery - Radial EBUS biopsy
Treatment: Devices - Types of Radial Ultrasound probes

Active comparator: Thick USS (1.7mm) with use of additional aspiration needle -

Active comparator: Thin USS (1.4mm) -


Treatment: Surgery: Radial EBUS biopsy
Radial EBUS is an endobronchial USS which is used to obtain biopsies from a peripheral lung mass.

Treatment: Devices: Types of Radial Ultrasound probes
The Radial USS probe comes in two sizes. A thick USS probe that is 1.7mm and the thin USS is 1.4mm in diameter.
