摘　　要：目的通过使用多层螺旋CT与MRI扫描对胰腺癌、慢性胰腺炎进行诊断,探讨其诊断价值。方法选取本院2017年4月至2019年7月收治的56例慢性胰腺炎及28例胰腺癌患者的临床资料,观察两种疾病的影像学检查表现,对比MSCT、MRI检查下两种疾病的诊断准确率。结果胰腺癌病变主要表现为胰腺体积增大、向周围组织及大血管侵犯、周围淋巴结肿大、胰胆管不规则扩张,慢性胰腺炎病变主要表现为病变及周围囊肿、胰胆管平滑状扩张,病变钙化;MSCT检查对慢性胰腺炎、胰腺癌诊断正确率分别为67.85%(38/56)、71.42%(20/28);MRI检查对慢性胰腺炎、胰腺癌诊断正确率分别为71.42%(40/56)、78.57%(22/28);MSCT+MRI检查对慢性胰腺炎、胰腺癌诊断正确率分别为94.64%(53/56)、92.85%(26/28),明显高于单一MSCT、MRI检查,差异有统计学意义(P<0.05)。结论MSCT和MRI扫描对胰腺癌和慢性胰腺炎的诊断和鉴别具有参考价值。两种检查相结合,可以提高对两种疾病的诊断准确性,为临床治疗提供参考依据。Objective Multi-slice spiral CT and MRI scan were used to diagnose pancreatic cancer and chronic pancreatitis,and its diagnostic value was explored.Methods The clinical data of 56 patients with chronic pancreatitis and 28 patients with pancreatic cancer admitted from April 2017 to July 2019 were selected.The imaging findings of the two diseases were observed,and the diagnostic accuracy of MSCT and MRI for the two diseases were compared.Results The main manifestations of pancreatic cancer were enlargement of volume of the pancreas,invasion of surrounding tissues and large blood vessels,swelling of surrounding lymph nodes,irregular expansion of pancreaticobiliary ducts.Chronic pancreatitis mainly showed lesions and surrounding cysts,smooth expansion of pancreaticobiliary duct,and calcification of lesions.The diagnostic accuracy of MSCT was 67.85%(38/56)and 71.42%(20/28)for chronic pancreatitis and pancreatic cancer.The diagnostic accuracy of MRI was 71.42%(40/56)and 78.57%(22/28)for chronic pancreatitis and pancreatic cancer.The diagnostic accuracy of MSCT+MRI for chronic pancreatitis and pancreatic cancer was 94.64%(53/56)and 92.85%(26/28),which was significantly higher than that of single MSCT and MRI.The difference was statistically significant(P<0.05).Conclusion MSCT and MRI scans have reference value for the diagnosis and identification of pancreatic cancer and chronic pancreatitis.The combination of the two examination can improve the diagnostic accuracy for the two diseases and provide reliable information for clinical treatment.
