A primer on linear array endosonographic anatomy

Endoscopic Ultrasound in the Clinical Staging and Management of Pancreatic Cancer: Its Impact on Cost of Treatment

“…The celiac artery trunk is easily identified as it exits the aorta using a linear array echoendoscope. 27 A 22gauge needle is passed through the biopsy channel and, under real-time guidance, is advanced through the gastric wall into the area surrounding the celiac trunk. Bupivacaine (0.25%) and ethyl alcohol (98%) can then be injected (Fig 11).…”

What should be known prior to performing EUS exams? (Part II)

“…To appreciate anatomical orientation with the new, unfamiliar longitudinal EUS systems, detailed descriptions of longitudinal EUS anatomy were published. [20,[23][24][25] However, despite the obvious advantage of the curved-array transducers introducing the most advanced ultrasound technology into the field of EUS, [26][27][28][29][30][31] many traditional users of radial scanning echoendoscopes were reluctant for a long time to use the new longitudinal echoendoscopes for noninterventional diagnostic purposes. In 2000, electronic array radial echoendoscopes became available, resulting in consequent improvements in image quality over traditional mechanical radial scanning echoendoscopes.…”
