A total of 62 patients with pancreatic tumor lesions and 37 control subjects were screened. In the former group, 10 patients were not eligible for the inclusion criteria (5 patients whose non-tumor pancreatic parenchyma was not sufficiently detected for SWE measurement because of the presence of pancreatic head tumor, 3 patients with surgical history, 1 patient without historical diagnosis, and 1 patient whose pancreatic tumor was not clearly detected by B-mode ultrasound (US)). In the latter group, 2 cases had surgical history and 2 cases had no laboratory data. Finally, a total of 52 patients with pancreatic tumor lesions and 33 control subjects were included in the study.
