“…The basic characteristics of EUS (origin 4 th layer and hypo-echogenicity) have a Se, Sp and Ac of 94,7%, 22,2% and 71,5% respectively; qualitative elastography showed Se, Sp and Ac of 71,1%, 44,4% and 62,5% respectively; elastography plus CE-hyperenhancement corresponded to Se, Sp and Ac of 61,1%, 66,7% and 63,0%; and if contrast diffusion was also evaluated as inhomogeneous Se, Sp and Ac were 41,7%, 83,3% and 55,5% respectively. 1 2 3 4…”
