摘　　要：目的探讨磁共振成像(MR)、弥散加权磁共振成像(DWI)鉴别诊断良恶性浅表软组织肿瘤的价值。方法选取2021年6月—2022年6月石家庄市人民医院收治的经病理证实的浅表软组织肿瘤患者80例作为研究对象,其中良性肿瘤组50例,恶性肿瘤组30例。所有患者行常规MR扫描和DWI检查,比较良性肿瘤组和恶性肿瘤组的MR影像学特征,比较2组最大强化率(ER_(max))、最大上升斜率(Slope_(max))和表观弥散系数(ADC)值,受试者工作特征曲线(ROC)分析ER_(max)、Slope_(max)、ADC鉴别良恶性软组织肿瘤的效能。结果良性肿瘤组和恶性肿瘤组在MR检查中肿瘤大小、肿瘤边界、肿瘤信号、侵袭性、强化方式比较差异均有统计学意义(P<0.05)。MR、DWI及MR结合DWI诊断恶肿瘤的符合率分别为66.7%、73.3%、83.3%;MR、DWI及MR结合DWI诊断良性肿瘤的符合率分别为76.0%、80.0%、88.0%,MR结合DWI检测均高于MR、DWI单项检测(Z=3.208、3.412,P<0.05)。良性肿瘤组ER_(max)、Slope_(max)值低于恶性肿瘤组,ADC值高于恶性肿瘤组(t/P=6.711/<0.001,4.220/<0.001,12.959/<0.001);ER_(max)、Slope_(max)、ADC及三者联合诊断鉴别良恶性软组织肿瘤的AUC值为0.827、0.744、0.768、0.933,三者联合高于单项检测(Z/P=4.212/<0.001,3.451/<0.001,3.425/<0.001)。结论MR、DWI参数有助于鉴别诊断良恶性浅表软组织肿瘤,联合ER_(max)、Slope_(max)、ADC值可提高诊断的准确性。Objective To explore the value of magnetic resonance imaging(MR)and diffusion weighted magnetic resonance imaging(DWI)in the differential diagnosis of benign and malignant superficial soft tissue tumors.Methods Eighty patients with pathologically confirmed superficial soft tissue tumors admitted to Shijiazhuang People's Hospital from June 2021 to June 2022 were selected as the study subjects,including 50 cases in the benign tumor group and 30 cases in the malignant tumor group.All patients underwent routine MR scanning and DWI examination to compare the MR imaging features of the benign and malignant tumor groups.The maximum enhancement rate(ER max),maximum slope of increase(Slope max),and apparent diffusion coefficient(ADC)values were compared between the two groups.The efficacy of subject operating characteristic curve(ROC)analysis of ER max,Slope max,and ADC in distinguishing benign and malignant soft tissue tumors was also evaluated.Results There were statistically significant differences in tumor size,tumor boundary,tumor signal,invasiveness,and enhancement mode between the benign tumor group and the malignant tumor group in MR examination(P<0.05).The coincidence rates of MR,DWI,and MR combined with DWI in diagnosing malignant tumors were 66.7%,73.3%,and 83.3%,respectively.The coincidence rates of MR,DWI,and MR combined with DWI in diagnosing benign tumors were 76.0%,80.0%,and 88.0%,respectively.MR combined with DWI detection was higher than MR and DWI single detection(Z=3.208,3.412,P<0.05).The ER max and Slope max values in the benign tumor group were lower than those in the malignant tumor group,while the ADC values were higher than those in the malignant tumor group(t/P=6.711/<0.001,4.220/<0.001,12.959/<0.001);The AUC values of ER max,Slope max,ADC,and their combination in the diagnosis and differentiation of benign and malignant soft tissue tumors were 0.827,0.744,0.768,and 0.933,which were higher than those of single detection(Z/P=4.212/<0.001,3.451/<0.001,3.425/<0.001).Conclusion MR and DWI parameters
