"Endoscopic ultrasound (EUS) is a procedure combining the range of endoscopy with the diagnostic abilities of ultrasound. EUS is used in the imaging of the upper GI tract and surrounding structures as well as the respiratory tract (where it is referred to as endobronchial ultrasound (EBUS)). A high-frequency transducer crystal is used, typically in the range of 12-20 megahertz."
"This article will be focusing on the upper GI use of EUS. For the respiratory tract, please refer to the article on endobronchial ultrasound (EBUS)."
