Extract

Endoscopic ultrasonography (EUS) is a unique imaging modality where a high-frequency ultrasound transducer is incorporated into the tip of an endoscope to provide high-resolution images of the GI wall and structures in close proximity to the GI tract above and below the diaphragm. EUS is the most accurate method for local tumor and lymph node staging of the GI cancers, with many other applications as well in the GI tract. The development of echoendoscopes that can image parallel to the long axis of the instrument allows visualization of a needle along its length, making EUS-guided intervention a clinical reality. Endosonography has evolved from a technological accomplishment to a clinically useful procedure for sampling peri-GI lymph nodes, pancreatic masses, and submucosal GI lesions, etc.16 EUS-guided injection of therapeutic substances has also begun.710
