MR elastography for pancreatic diseases

Palpation, feeling tissue stiffness by the hand, is a basic skill we’ve been trained at medical school. It provides important clue for disease detection and characterization. Pancreas, a deeply-situated retroperitoneal organ, however, is only reachable by surgeons’ hands at open surgery. MR elastography (MRE) provides a method of virtual palpation, which reflects tissue stiffness and other biophysical properties in a precise, quantitative manner. Here I am going to present several clinical applications of MRE in pancreatic diseases, including predicting the risk of postoperative pancreatic fistula, detecting pancreatic cancer and defining its invasive border, and distinguishing pancreatic cancer from its renowned mimicker, mass-forming autoimmine pancreatitis. I am also going to demonstrate the advantages of tomoelastography, with multi-frequency acquisition and high-resolution parametric maps, over the conventional single-frequency MRE.
