Elastography with endoscopic ultrasonographic (EUS) shear wave measurement (SWM), obtained with the ultrasonographic observation system ARIETTA 850 (Hitachi Aloka Medical Ltd.). In this EUS image, the pancreas (outlined by the rectangle) has mixed signals with hyperechoic foci, strands, and dilated side branches. EUS-SWM was performed to diagnose early chronic pancreatitis. The EUS-SWM value of 2.24 was higher than the cutoff value of 2.19 for diagnosing chronic pancreatitis [11].
