Value of DWI in the Diagnosis of Mass Forming Pancreatitis and Pancreatic Cancer
Objective To observe the value of DWI in the diagnosis of mass forming pancreatitis(MFP)and pancreatic cancer.Methods The medical records of 41 patients with MFP and 55 patients with pancreatic cancer who were examined in Imaging Department of Dongtai People's Hospital from March 2020 to March 2023 were analyzed.Imaging characteristics and apparent diffusion coefficient(ADC)values of the two groups were compared.Binary logistic analysis of the differential diagnosis of MFP and pancreatic cancer was conducted.The performance of conventional DWI and ADC value in diagnosing pancreatic cancer was analyzed using the receiver operating characteristic curve.Results The proportion of mixed high signal on T2WI in pancreatic cancer group was significantly higher than that in pancreatitis group(P＜0.05).ADC value in pancreatic cancer group was significantly higher than that in pancreatitis group(P＜0.05).Binary logistic analysis showed that mixed with high signal on T2WI and ADC value were independent influencing factors for differential diagnosis of MFP and pancreatic cancer(P＜0.05).The AUC and specificity of conventional DWI combined with ADC value in diagnosing pancreatic cancer were 0.843 and 92.1％,higher than those of single diagnosis.Conclusion DWI is helpful for differential diagnosis of MFP and pancreatic cancer.It is expected to provide reference for early diagnosis and treatment of pancreatic cancer.
