Prospective, randomized comparison of mechanical and electronic radial endoscopic ultrasound systems: Assessment of performance parameters and image quality

Abstract

Electronic EUS provided better quality images according to the examiner's subjective assessment. An objective advantage was faster identification of the distal CBD.

A comparison of electronic radial and curvilinear endoscopic ultrasonography in the detection of pancreatic malignant tumor

“…However, ER-EUS with color-Doppler and harmonic imaging is now available, and there is no comparative study of ER-EUS and EC-EUS. There were only a few reports that showed ER-EUS could provide better images than mechanical radial EUS [16,17]. Thus, it is unknown whether ER-EUS is equivalent or superior for the detection of pancreatic malignancy, compared with EC-EUS.…”

“…With recent advances of EUS technology, electronic radial echoendoscope with the ability of harmonic and color-Doppler imaging have been developed [15], and a few studies showed it could provide better quality images, compared with the mechanical radial echoendoscope in the diagnosis of pancreatic lesions [16,17]. Therefore, the diagnostic accuracy of radial EUS with electronic ultrasound system may be improved, and better than EC-EUS in the diagnosis of pancreatic malignancies.…”

An Electronic Radial Scanning Echoendoscope Is Superior to a Mechanical Radial Scanning Echoendoscope in Ultrasound Image Quality for Gastrointestinal Tract and Pancreaticobiliary Lesions

“…1 point : Artifact is too strong, and on the inside is not understood. with a scanning range of 360 degrees was introduced, and Papanikolaou et al reported its excellent image quality in normal structures in the pancreas, common bile duct, gastric wall, and esophageal wall 21) . We wished to objectively evaluate the ER -ES not with normal structures but with lesions, 2) Lesion's echo 5 points : It is clear.…”

“…Papanikolaou et al reported the excellent image quality of the ER -ES with a scanning range of 360 degrees ; however, they used normal structures, not lesions 21) . Therefore, the aim of this study was to compare the ER -ES and MR -ES, each with a scanning range of 360 degrees, in the quality of EUS images of gastrointestinal tract and pancreaticobiliary lesions.…”

This month in Scandinavian Journal of Gastroenterology

“…Papanicolau et al [12] examine image quality and performance and compare between of an electronic and a mechanical radial echoendoscope Electronic EUS provided better quality images according to the examiner's subjective assessment. EUS availability, accessibility and utilization among clinicians from different European countries were assessed.…”
