TLDR
In this article, a contrast-enhanced harmonic EUS system was used to diagnose pancreatic carcinomas as hypovascular masses with a high sensitivity (89-96%) and specificity (64-88%).Abstract:
Although endoscopic ultrasonography (EUS) has the advantage over other imaging methods in that it is possible to obtain high resolution images of the pancreas, it is limited in its ability to characterize pancreatic masses. Contrast-enhanced power Doppler ultrasonography suffers from several limitations such as blooming artifacts, poor spatial resolution, low sensitivity to slow flow and high sensitivity to motion artifacts. Recently, EUS system specific for contrast harmonic imaging has been developed. The use of this EUS system enabled us to observe images of microcirculation and parenchymal perfusion without Doppler-related artifacts in the pancreas. Contrast-enhanced harmonic EUS could diagnose pancreatic carcinomas as hypovascular masses with a high sensitivity (89-96%) and specificity (64-88%). Contrast-enhanced harmonic EUS also discriminates mural nodules from mucous clots in the intraductal papillary mucinous neoplasms.read more

Contrast-enhanced endoscopic ultrasound
TL;DR: CE‐EUS is useful for characterizing pancreatic lesions and can detect pancreatic adenocarcinomas with a sensitivity and specificity of 94% and a specificity of 89% as a result of the hypo‐enhancement of these lesions.

TL;DR: Endoscopic ultrasonography is a highly sensitive and specific procedure for the localization of pancreatic endocrine tumors and should be considered for the preoperative localization of such tumors once the clinical and laboratory diagnosis has been established.

TL;DR: EUS is superior to US and CT and equal to ERCP in pancreatic tumor diagnosis and provides direct visualization of tumor size and shape in almost all patients examined, and should be considered early in the evaluation of patients with suspected pancreatic tumors.

TL;DR: Endoscopic ultrasonography is an accurate tool for diagnosis and locoregional spread assessment of pancreatic cancer when performed in a reference center, however, EUS does not enable differentiation of pseudotumorous pancreatitis from adenocarcinoma.
