Prospective cohort study comparing transient EUS guided elastography to EUS-FNA for the diagnosis of solid pancreatic mass lesions

EUS-guided Realtime Elastography (SonoElastography, HITACHI EUB-7500) is a method for calculating the displacement of ultrasound signals returned from the examined structures before and after compression. Calculation of the reconstructed strain field is assessed quantitatively and is expressed as strain ratio (SR). EUS guided FNA is usually employed to obtain diagnostic tissue from solid pancreatic lesions prior to treatment, but sampling errors occur in >10%. We evaluated whether EUS-guided transient elastography would increase the diagnostic accuracy for solid pancreatic mass lesion compared to EUS-FNA and B-M…
