摘　　要：目的 对比多层螺旋CT、磁共振检查对MPNST的诊断价值。方法 回顾分析本院2017年1月至2019年7月收治的30例MPNST患者的临床资料,所有患者均进行MSCT及MRI检查。对患者所得图像进行分析,记录患者检查结果,将MSCT、MRI检查结果和病理结果进行比较,并对比MSCT、MRI检查对MPNST诊断的灵敏度、特异度、准确率、阳性预测值以及阴性预测值进行比较。结果MSCT检查中MPNST患者确诊有6例,其诊断准确率为63.33%(19/30),漏诊率为40.00%(4/10),误诊率为35.00%(7/20);MRI检查中MPNST患者确诊有9例,其诊断准确率为86.66%(26/30),漏诊率为10.00%(1/10),误诊率为15.00%(3/20)。MSCT、MRI检查在灵敏度、特异度、阳性、阴性预测值上比较,差异无统计学意义(P>0.05);两者准确率比较,MRI准确率为86.66%(26/30),明显高于MSCT检查63.33%(19/30)(P<0.05)。结论 MRI检查准确率高于MSCT,且漏诊率、误诊率低,对MPNST有着较高的诊断价值。Objective To compare the diagnostic value between multi-slice spiral CT and magnetic resonance imaging for MPNST. Methods The clinical data of 30 patients with MPNST admitted to our hospital from January 2017 to July 2019 were retrospectively analyzed. All patients underwent MSCT and MRI.The images obtained by the patients were analyzed, the results of the patients were recorded, the results of MSCT and MRI were compared with the pathological results, and the sensitivity, specificity,accuracy, positive predictive value and negative predictive value of MSCT and MRI examinations in the diagnosis of MPNST were compared. Results In the MSCT examination, 6 patients were diagnosed with MPNST, the diagnostic accuracy was 63.33%(19/30), the missed diagnosis rate was 40.00%(4/10), the misdiagnosis rate was 35.00%(7/20). In the MRI examination, 9 patients were diagnosed with MPNST,the diagnostic accuracy was 86.66%(26/30), the missed diagnosis rate was 10.00%(1/10), and the misdiagnosis rate was 15.00%(3/20). There was no significant difference in the sensitivity, specificity,positive and negative predictive value between MSCT and MRI(P>0.05). The accuracy of MRI was86.66%(26/30), which was significantly higher than that of MSCT(63.33%(19/30)(P<0.05). Conclusion The accuracy of MRI examination is higher than that of MSCT, and the rate of missed diagnosis and misdiagnosis is low, which has higher diagnostic value for MPNST.
