In this prospective study,ten healthy volunteers and 26 patients with pancreatic masses undertook MR Elastography on a 3T scanner to evaluate its usefulness for differentiating benign and malignant solid pancreatic lesions. The mean stiffness value of healthy pancreas was (1.120.11) kPa. Malignant lesion[(2.701.20) kPa] has much higher stiffness than both mass-forming pancreatitis[(1.590.31) kPa] and healthy pancreas.Mass-forming pancreatitis has slightly higher stiffness than healthy pancreas, but with apparent overlapping.Our study proved MR elastography might be a potential tool to different solid pancreatic masses.
