摘要

Elastography is one of technologies assisting diagnosis ofsolid pancreatic lesions(SPL). This technology has been previously used for measuring the stiffness of various organs based on a principle of 'harder the lesions, higher chance for malignancy'. Two elastography techniques; strain and shear wave elastography, are available. For endoscopic ultrasound(EUS), only the former is existing. To interpret results of EUS elastography for SPL, 3 methods are used:(1) pattern recognition;(2) strain ratio; and (3) strain histogram. Based on results of existing studies, these 3 techniques provide high sensitivity but low to moderate specificity and accuracy rate. This review will summarize all available information in order to update current situation of using elastography for an evaluation of SPLs to readers.
