Efficacy of shear wave elastography for the diagnosis of chronic pancreatitis.

Abstract

Shear wave elastography (SWE) is a clinical method used to evaluate liver hardness. In this study, we assessed its applicability in assessing the pancreas and its potential for diagnosing chronic pancreatitis. We performed SWE on 59 patients who underwent abdominal ultrasound, and measured the computed tomography (CT) values of the pancreas. Patients were classified as having a normal pancreas (NP), early chronic pancreatitis (ECP), or chronic pancreatitis (CP). SW elasticity (SWe), SW dispersion (SWd), and CT values between groups were analyzed. SWe significantly differed between the CP and NP/ECP groups (NP vs CP; P=0.001, ECP vs CP; P=0.026,), while SWd showed a significant difference only between the NP and CP group (NP vs CP; P=0.001). The CT values were significantly different between the CP and NP/ECP groups (NP vs CP; P=0.0006, ECP vs CP; P=0.0027). Pancreatic SWE and CT values were helpful in the diagnosis of chronic pancreatitis. SWd may reveal status changes in ECP.
