The use of contrast enhanced endoscopic ultrasound in discrimination between focal pancreatitis and pancreatic cancer

Aim: The aim of this study was to evaluate contrast-enhanced endosonography as a method of differentiating inflammation and pancreatic carcinoma based on perfusion characteristics of microvessels. Patients and Method: In 192 patients with suspected chronic pancreatitis [age: 64±11 years; sex: f/m 75/117] pancreatic lesions were examined by conventional endoscopic B-mode and Power Doppler ultrasound and contrast enhanced power mode (Hitachi EUB 525, SonoVue®, 2.4ml, Bracco) using the following criteria for malignant lesions: no detectable vascularisation using conventional power Doppler scanning, irregular appear…
