Application Value of Multi-slice Spiral CT and Diffusion Weighted Magnetic Resonance Imaging in Pancreatic Neuroendocrine Tumors
Objective To analyze the application value of multislice spiral CT(MSCT)and diffusion weighted imaging(DWI)in the diagnosis of pancreatic neuroendocrine tumors(pNEN).Methods The clinical data of 80 pNEN patients admitted to our hospital from July 2021 to November 2022 were taken as the observation group,and MSCT and DWI tests were performed on all patients.To analyze the application value of two examination methods for this disease.Results A comparison of various MSCT parameters in patients with different pathological grades showed that there were significant differences in tumor margin,shape,cystic necrosis,main pancreatic duct dilation,maximum diameter of distant metastatic tumors,and arterial and portal phase values with absolute CT enhancement(P＜0.05).The univariate analysis of variance showed that there were significant differences in the ADC values of DWI examination among patients with different pathological grades,with G1 and G2 patients significantly higher than G3 patients,and G2 patients significantly higher than G3 patients(P all＜0.05).Incorporate the two examination parameter indicators into the logistic regression model to obtain a joint prediction value,and then conduct ROC curve analysis.It is shown that with G3 patients as the detection variable and the remaining graded patients as the reference variable,the joint prediction AUC reaches 0.927;The predictive sensitivity was 92.3％and the specificity was 81.2％.Conclusion MSCT and DWI are both valuable in the predictive diagnosis of pNEN patients.However,in order to avoid the limitations of a single detection method,it is recommended to combine other detection methods in clinical diagnosis.
