A Novel Endoscopic Ultrasonography Imaging Technique for Depicting Microcirculation in Pancreatobiliary Lesions without the Need for Contrast-Enhancement: A Prospective Exploratory Study

Detective flow imaging endoscopic ultrasonography (DFI-EUS) provides a new method to image and detect fine vessels and low-velocity blood flow without using ultrasound contrast agents. The aim of this study was to evaluate the utility of DFI-EUS for pancreatobiliary lesions and lymph nodes. Between...

The aim of this study was to evaluate the utility of DFI-EUS for pancreatobiliary lesions and lymph nodes. Between January 2019 and January 2020, 53 patients who underwent DFI-EUS, e-FLOW EUS, and contrast-enhanced EUS were enrolled.

This article describes the DFI technique along with our first experience of its use for vascular assessment of pancreatobiliary lesions. Vessels were imaged in 34 pancreatic solid lesions, eight intraductal papillary mucinous neoplasms (IPMNs), seven gall bladder lesions, and four swollen lymph nodes. DFI-EUS (91%) was significantly superior to e-FLOW EUS (53%) with respect to detection of vessels (<i>p</i> < 0.001) and for discrimination of mural nodules from mucous clots in IPMN and gallbladder lesions from sludge (<i>p</i> = 0.046). Thus, DFI-EUS has the potential to become an essential tool for diagnosis and vascular assessment of various diseases.Yasunobu YamashitaTakanori YoshikawaHirofumi YamazakiYuki KawajiTakashi TamuraKeiichi HatamaruMasahiro ItonagaReiko AshidaYoshiyuki IdaTakao MaekitaMikitaka IguchiMasayuki KitanoMDPI AGarticledetective flow imaging endoscopic ultrasonographydoppler endoscopic ultrasonographyvessel detectionnovel techniquecontrast-enhanced endoscopic ultrasonographypancreatobiliary lesionMedicine (General)R5-920ENDiagnostics, Vol 11, Iss 2018, p 2018 (2021)
