Preliminary Evaluation of Acoustic Radiation Force Impulse Shear Wave Imaging to Detect Hepatic Fibrosis in Morbidly Obese Patients Before Bariatric Surgery

摘要

Background and Aims: Acoustic Radiation Force Impulse (ARFI) shear wave imaging is a noninvasive method of assessment of the liver to detect fibrosis in patients with chronic hepatitis and nonalcoholic fatty liver disease (NAFLD). The aim of this retrospective study was to investigate whether noninvasive measurement of shear wave velocity (SWV) by ARFI shear wave imaging has a potential usefulness for detection of fibrosis secondary to NAFLD in patients with morbid obesity.
