摘　　要：目的探讨在胰腺良性恶性肿块鉴别诊断中1.5 T超导磁共振扩散加权成像(DWI)的临床应用价值。方法选取2018年1月至2019年10月该院收治的胰腺肿块患者64例作为6研究对象,给予1.5 T DWI、CT检查,以病理组织检查结果作为"金标准",对两种方法的鉴别诊断情况进行对比分析。结果恶性肿块组患者ADC值及直径、CT影像学表现与良性肿块组比较,差异均有统计学意义(P<0.05);DWI检查诊断恶性肿块率与病理检查比较,差异无统计学意义(P>0.05);CT检查诊断恶性肿块率明显低于病理检查,差异有统计学意义(P<0.05);DWI检查诊断恶性肿块的灵敏度、特异度、良性预测值与恶性预测值分别为91.11%、63.16%、85.42%、75.00%;CT检查诊断恶性肿块的灵敏度、特异度、良性预测值与恶性预测值分别为88.89%、31.58%、75.47%、54.55%,二者比较,差异均有统计学意义(P<0.05)。结论在胰腺良恶性肿块的鉴别诊断中1.5 T DWI具有较高的灵敏度、特异度,值得推广应用。Objective To investigate the clinical value of 1.5 T diffusion weighted imaging(DWI)in the differential diagnosis of benign and malignant pancreatic masses.Methods A total of 64 patients with pancreatic mass received in our hospital from January 2018 to October 2019 were selected as the research objects,and 1.5 T DWI and CT were provided for them,and the differential diagnosis of the two methods was compared based on the results of pathological examination.Results According to DWI imaging results,there was a significant difference in ADC value and diameter between malignant mass group and benign mass group(P<0.05);according to CT imaging results,there was a certain imaging difference between malignant mass group and benign mass group;according to the results of pathological examination,the rate of malignant mass was 29.69%,DWI imaging malignant mass was 29.69%The sensitivity,specificity,benign predictive value and malignant predictive value of DWI imaging were 91.11%,63.16%,85.42%and 75.00%,respectively,and the sensitivity,specificity,benign predictive value and malignant predictive value of CT imaging were 88.89%,31.58%,75.47%and 54.55%,respectively There was statistical significance(P<0.05).Conclusion In the differential diagnosis of benign and malignant pancreatic masses,1.5 T DWI has high sensitivity and specificity,which is worth popularizing.
