Contrast-enhanced endoscopic ultrasound in discrimination between focal pancreatitis and pancreatic cancer

Table 1 Endosonographic criteria for differentiation between malignant and benign diseases

Kind of lesion	Vessel architecture using conventional power mode	Arterial or venous in the lesion using continuous duplex scanning	Vessel architecture using contrastenhanced power mode
Pancreatic cancer	No visible vascularisation	Only arterial vessels	Irregular, chaotic vessels
Focal pancreatitis	Nearly no visible vascularisation	Both arterial and venous vessels in the lesion	Regular with no changing diameter
