摘　　要：目的探究3.0TMR动态增强(DCE-MRI)及扩散加权成像(DWI)联合外周血炎症指标对腮腺良恶性肿瘤的鉴别诊断价值。方法选取本院2020年10月至2023年10月收治的92例腮腺肿瘤患者,患者均行DCE-MRI和DWI检查;全自动血细胞分析仪检测外周血炎症指标;绘制ROC曲线分析DCE-MRI、DWI以及外周血炎症指标对腮腺肿瘤鉴别诊断的阈值;四格表分析DCE-MRI及DWI联合外周血炎症指标对腮腺肿瘤的鉴别诊断效能。结果多形性腺瘤呈A型30例,C型4例;腺淋巴瘤呈B型28例,C型12例;恶性肿瘤呈B型1例,C型17例。恶性肿瘤表观弥散系数(ADC)显著低于良性肿瘤(P<0.05);ADC鉴别诊断腮腺良恶性肿瘤的AUC为0.890。腮腺良性肿瘤和恶性肿瘤间Kep和Ve比较有差异(P<0.05);Kep和Ve鉴别诊断腮腺良恶性肿瘤的AUC为0.851和0.870。腮腺恶性肿瘤患者PLR、NLR和SIRI显著高于良性肿瘤患者(P<0.05)。PLR、NLR和SIRI鉴别诊断腮腺良恶性肿瘤的AUC为0.854、0.890和0.864。DCE-MRI、DWI、PLR、NLR和SIRI鉴别诊断腮腺良恶性肿瘤准确度为90.22%、88.04%、85.87%、83.70%、86.96%;五者联合鉴别诊断腮腺良恶性肿瘤准确度为94.57%。结论腮腺肿瘤患者外周血PLR、NLR和SIRI显著升高,DCE-MRI及DWI联合PLR、NLR和SIRI可有效提高腮腺良恶性肿瘤的鉴别诊断价值。Objective To explore the differential diagnostic value of 3.0T MR dynamic contrast-enhanced imaging(DCE-MRI)and diffusion-weighted imaging(DWI)combined with peripheral blood inflammatory markers for benign and malignant parotid gland tumors.Methods A total of 92 patients with parotid gland tumors admitted to our hospital from October 2020 to October 2023 were gathered,and all patients underwent DCE-MRI and DWI examinations.Fully automatic blood cell analyzer was applied to detect peripheral blood inflammation indicators.ROC curve was plotted to analyze the thresholds of DCE-MRI,DWI,and peripheral blood inflammation indicators for differential diagnosis of parotid gland tumors.Four grid table was applied to analyze the differential diagnostic efficacy of DCE-MRI and DWI combined with peripheral blood inflammation indicators for parotid gland tumors.Results There were 30 cases of pleomorphic adenoma with type A and 4 cases with type C;28 cases of adenolymphoma were B-type and 12 cases were C-type;1 case of malignant tumor was type B,and 17 cases were type C.The apparent diffusion coefficient(ADC)of malignant tumors was obviously lower than that of benign tumors(P<0.05);the AUC for differential diagnosis of benign and malignant parotid gland tumors by ADC was 0.890.There was a difference in K_(ep)and V_e between benign and malignant tumors of the parotid gland(P<0.05);the AUC for differential diagnosis of benign and malignant parotid gland tumors using K_(ep)and V_e was 0.851 and 0.870,respectively.The PLR,NLR,and SIRI of patients with parotid gland malignant tumors were obviously higher than those of patients with benign tumors(P<0.05).The AUC for differential diagnosis of benign and malignant parotid gland tumors using PLR,NLR,and SIRI was 0.854,0.890,and 0.864,respectively.The accuracy of differential diagnosis of benign and malignant parotid gland tumors using DCE-MRI,DWI,PLR,NLR,and SIRI was 90.22%,88.04%,85.87%,83.70%,and 86.96%,respectively;the accuracy of the combined differential diagnosis of benign and mal
