摘　　要：目的分析CT影像学鉴别慢性胰腺炎与胰腺癌的应用价值,为临床诊断提供参考。方法选取本院在2018年1月—12月收治患者120例为研究对象,依照疾病类型划分为胰腺炎组70例和胰腺癌组50例,两组患者均采用CT影像学检查。结果直接征象包括病变区肿大、胰腺肿大、假性囊肿、密度不均匀等。胰腺炎组患者病变区肿大、密度不均匀、胰管远端扩张均匀、胆总管扩张突然中断、周围脂肪层受累、大血管受累征象发生率均显著低于胰腺癌组,差异有统计学意义(P<0.05),胰腺炎组患者胰管全长不均匀扩张、假性囊肿、胰腺钙化、胰后肾前筋膜增厚征象发生率均显著高于胰腺癌组,差异有统计学意义(P<0.05)。结论慢性胰腺炎和胰腺癌CT影像学表现存在一定差异,鉴别诊断时应结合CT征象综合判断。Objective To analyze the value of CT imaging in differentiating chronic pancreatitis from pancreatic cancer,and to provide reference for clinical diagnosis.Methods 120 patients admitted to the hospital from January 2018 to December 2018 were selected as the research objects.According to the type of disease,they were divided into the pancreatitis group(70 cases)and the pancreatic cancer group(50 cases).Both groups of patients were examined by CT imaging.Results The direct signs included enlargement of the lesion area,pancreas enlargement,pseudocyst and uneven density.In the pancreatitis group,the lesion area was enlarged,the density was uneven,the distal end of the pancreatic duct was evenly expanded,the common bile duct was suddenly interrupted,the surrounding fat layer was involved,and the incidence of large vessel involvement was significantly lower than that of the pancreatic cancer group.The difference was statistically significant(P<0.05),the incidence of uneven pancreatic duct dilatation,pseudocyst,pancreatic calcification,and pancreatic pre-renal fascia thickening was significantly higher in the pancreatitis group than in the pancreatic cancer group.The difference was statistically significant(P<0.05).Conclusion There are some differences in CT imaging manifestations between chronic pancreatitis and pancreatic cancer,and the differential diagnosis should be combined with CT signs.
