Endoscopic ultrasound elastography in solid pancreatic lesions: individual and combined performance of strain ratio, fat-lesion strain ratio, and mean strain histogram for diagnosing pancreatic ductal adenocarcinoma.

ABSTRACT: This study aims to compare three different elastography parameters to evaluate their efficacy in diagnosing Pancreatic Ductal Adenocarcinoma (PDAC) and provide a semi-quantitative or quantitative assessment method for endoscopic ultrasound elastography. We retrospectively analyzed patients with PDAC, patients with benign pancreatic diseases, and individuals with normal pancreas who underwent endoscopic ultrasound elastography at the First Affiliated Hospital of Xi'an Jiaotong University between June 2022 and March 2023. Elastography parameters collected included strain ratio (SR), fat-lesion strain ratio (FLR), and mean strain histogram value (MEAN). Overall, 102 patients were enrolled, comprising 74 patients with PDAC (malignant group), 15 patients with benign lesions, and 13 patients wit
