摘要
目的 分析磁共振与经腹部彩超对胰腺癌与肿块型胰腺炎的临床鉴别诊断价值。方法 选取2018年1月-2021年1月万载县人民医院收治的80例胰腺肿块型病变患者,其中胰腺癌40例,肿块型胰腺炎40例,所有患者均给予磁共振与经腹部彩超检查,观察不同患者的影像学表现,并以病理检查为金标准,分析其鉴别诊断效能。结果 肿块型胰腺炎与胰腺癌患者后方回声及血流信号比较,差异有统计学意义(P<0.05);肿块型胰腺炎患者的不规则扩张并贯通率、胰管结石率高于胰腺癌患者,光滑扩张并中断率、腹腔淋巴肿大率低于胰腺癌患者,差异有统计学意义(P<0.05);肿块型胰腺炎患者的ADC值高于胰腺癌患者,差异有统计学意义(P<0.05);肿块型胰腺炎与胰腺癌患者T_(2)WI序列、增强动脉期及增强门静脉期病变信号特征比较,差异有统计学意义(P<0.05);磁共振检查对肿块型胰腺炎与胰腺癌疾病的诊断准确性、敏感度、特异度均高于经腹部彩超,差异有统计学意义(P<0.05)。结论 磁共振与经腹部彩超均可有效鉴别胰腺癌与肿块型胰腺炎,其中磁共振成像的诊断效能相对更高。
Objective To analyze the clinical value of MRI and transabdominal ultrasonography in the differential diagnosis of pancreatic carcinoma and mass-type pancreatitis.Methods A total of 80 patients with pancreatic mass lesions admitted to Wanzai County People’s Hospital from January 2018 to January 2021 were selected,including 40 patients with pancreatic cancer and 40 patients with mass-type pancreatitis.All patients were examined by magnetic resonance and transabdominal color Doppler ultrasound.The imaging findings of different patients were observed,and the differential diagnostic efficacy was analyzed with pathological examination as the gold standard.Results There were statistically significant differences in posterior echo and blood flow signals between mass-type pancreatitis and pancreatic cancer( P<0.05).The irregular expansion and penetration rate and pancreatic duct stone rate in patients with mass-type pancreatitis were higher than those in patients with pancreatic cancer,and the smooth expansion and interruption rate and abdominal lymphadenopathy rate were lower than those in patients with pancreatic cancer,the differences were statistically significant(P<0.05).The ADC value of patients with mass-type pancreatitis was higher than that of patients with pancreatic cancer,and the difference was statistically significant(P<0.05).There were significant differences in T_(2)WI sequence,enhanced arterial phase and enhanced portal venous phase signal characteristics between patients with mass-type pancreatitis and pancreatic cancer( P<0.05).The diagnostic accuracy,sensitivity and specificity of MRI for mass-type pancreatitis and pancreatic cancer were higher than those of transabdominal ultrasonography( P <0.05).Conclusion Both MRI and transabdominal ultrasonography can effectively differentiate pancreatic cancer from mass-type pancreatitis,and MRI has higher diagnostic efficiency.
