Comparison of image quality between electronic and mechanical radial scanning echoendoscopes in pancreatic diseases

Background and Aim: It is common knowledge that endoscopic ultrasonography (EUS) can accurately diagnose pancreatic diseases. Echoendoscopes for EUS are roughly classified into two categories, the mechanical radial scanning echoendoscope (MR‐ES) and the electronic linear array echoendoscope, both of which have their merits and demerits. In 2000, a newly designed echoendoscope, the electronic radial scanning echoendoscope (ER‐ES), appeared. The aim of the present study was to compare B‐mode image quality between the ER‐ES and the MR‐ES in pancreatic diseases.
