摘　　要：目的探讨体素内不相干运动弥散成像(IVIM-DWI)多参数鉴别诊断腮腺Warthin瘤与多形性腺瘤的价值。方法回顾性分析病理学证实的腮腺Warthin瘤19例、多形性腺瘤18例的IVIM-DWI资料,分析f值、D值、D*值及A。结果对照组左右两侧各参数差异无统计学意义(P>0.05);Warthin瘤、对照组、多形性腺瘤三组间f值差异有统计学意义(P<0.05);Warthin瘤与对照组间D值、A差异无统计学意义(P>0.05),多形性腺瘤与对照组、多形性腺瘤与Warthin瘤间D值、A差异有统计学意义(P<0.05),三组间D*值差异无统计学意义(P>0.05);分别以f值=2.203%、D值=0.908×10^(-3)mm^(2)/s、A=20.12为阈值及联合三者,鉴别Warthin瘤与多形性腺瘤的曲线下面积(AUC)分别为0.823、0.887、0.884、0.927(P<0.05),敏感度分别为88.89%、88.89%、83.33%、88.89%,特异度分别为72.00%、96.00%、100%、88.00%。结论IVIM-DWI多参数及联合应用有助于鉴别Warthin瘤与多形性腺瘤。Objective To investigate the value of multiparametric features of IVIM-DWI in differentiation between parotid Warthin tumor and pleomorphic adenoma.Methods Thirty-seven patients were included in this study including 19 cases with parotid Warthin tumors and 18 cases with pleomorphic adenomas.Multiparameters of IVIM-DWI were analyzed.Differences in parameters(f,D,D*,A)between the right side and the left side of the normal parotid glands were determined by paired samples t-test.Differences in parameters between Warthin tumors and pleomorphic adenomas were determined by independent samples t-test.Results Differences in all parameters between the two sides of the normal parotid glands were not significant(P>0.05).The values of f were significantly different between Warthin tumors,pleomorphic adenomas and normal control(P<0.05).The values of D and A were not significantly different between Warthin tumors and normal control(P>0.05),but were significantly different between pleomorphic adenomas and normal control,between Warthin tumors and pleomorphic adenomas(P<0.05).Differences in D*of the three groups were not significant(P>0.05).Taking f=2.203%,D=0.908×10^(-3) mm^(2)/s,A=20.12,as threshold and taking f combined with D and A drawing ROC for differential diagnosis of Warthin tumor and PA of parotid gland,the area under curve(AUC)were 0.823,0.887,0.884,0.927(P<0.05),sensitivity were 88.89%,88.89%,83.33%,88.89%,specificity were 72.00%,96.00%,100%,88.00%.Conclusion Multiparameters of IVIM-DWI were helpful to differential d iagnosis of Warthin tum or and pleo morphic adenoma of parotid.
