Abstract: ［Abstract］Objective〖HTSS〗To investigate  the value of acoustic palpation tissue quantitative(VTQ) in differentiating focal pancreatic lesions.
〖HTH〗〖WTHZ〗Methods〖HTSS〗Eighty patients with pancreatic focal lesions treated in our hospital were selected as the research objects. The benign and malignant lesions of pancreatic focal lesions were analyzed. Thirtyeight patients with benign lesions were included in the benign group, and the remaining 42 patients with malignant lesions were included in the malignant group. All patients underwent VTQ diagnosis after admission, and the repeatability of shear wave velocity(SWV) measurements was analyzed to differentiate the diagnostic value of SWV, SWV in adjacent pancreatic parenchyma and SWV difference in focal pancreatic lesions.
〖HTH〗〖WTHZ〗Results〖HTSS〗The age and diameter of malignant group were significantly higher than those of control group(P＜0.05) . The SWV value and SWV difference between malignant group and peripheral pancreatic parenchyma were significantly higher than those of benign group(P＜0.05) . The SWV value and SWV difference between pancreatic cancer and peripheral pancreatic parenchyma were significantly higher than those of pancreatic parenchyma(P＜0.05). The SWV value and SWV difference between pancreatic cancer lesions and surrounding pancreatic parenchyma were significantly higher than those of pancreatic inflammatory lesions(P＜0.05).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗SWV has good reproducibility and accuracy in the differential diagnosis of pancreatic focal lesions. The application of VTQ can provide data support for clinicians to differentiate benign and malignant pancreatic lesions, and has positive significance for the formulation and improvement of followup treatment plan of patients. It can be considered for clinical application.
