Radial endobronchial ultrasound of a peripheral pulmonary lesion

Panel A shows a representative image of a bronchoscope with a radial endobronchial ultrasound probe (left) and sheath (right). Panels B and C show a computed tomographic (B) and corresponding radial ultrasound (C) image of a peripheral pulmonary lesion. The radial ultrasound image demonstrates a fairly well circumscribed echoic lesion with the hyper echoic (brighter white) boundary between the aerated lung and the lesion.
