Value of <sup>18</sup>F-FDG PET-CT and MR Fusion in Preoperative Diagnosis and Staging of Pancreatic Cancer

Abstract

<i>Background:</i> With the improvement of medical level, the incidence of some tumors decreased significantly; However, in the actual clinical work, it was found that the incidence and mortality of pancreatic cancer is increasing, and most of the findings are in the late stage, so the following studies have solved its current situation, so as to early detection, early treatment, improve the survival rate of patients; Secondly, better clinical staging, so as to reasonably select treatment methods. <i>Objective: </i>To use 18 fluoro-deoxyglucose (¹⁸F-FDG) positron emission computed tomography (PET-CT) molecular metabolism imaging and MRI multi-parameter structure imaging, and then use different machine fusion technology to realize the comprehensive application of pancreatic cancer diagnosis and staging. <i>Methods: </i>A retrospective comparative study was conducted on 100 patients with pancreatic space occupying diagnosed in our center. All patients received enhanced MR Examination and ¹⁸F-FDG PET-CT examination before surgery, and underwent different machine image fusion. <i>Results: </i>The sensitivity, specificity and accuracy of PET-CT and MRI in the diagnosis of pancreatic cancer were higher than those of PET-CT alone (P < 0.05). <i>Conclusion: </i>The PET-CT and MRI fusion technology can be used in the diagnosis of pancreatic cancer, which can be accurately staged and provide help for early clinical diagnosis and treatment.
