Objective To investigate the application value of quantitative relaxation parameters based on synthetic MRI technology in the differential diagnosis of parotid gland tumors.Methods Conventional MRI and synthetic MRI data of 59 patients with patho-logically confirmed parotid gland tumors were analyzed retrospectively.T1,T2,and proton density(PD)values of the tumor were extracted from T1,T2 and PD mapping.The differences in quantitative relaxation parameters of pleomorphic adenomas,Warthin tumors,and malignant tumors were further compared.Diagnostic performance of each quantitative relaxation parameter was assessed and com-pared via receiver operating characteristic(ROC)curve and DeLong test.Results T2 value was significantly higher in pleomorphic adenomas than that in malignant tumors(P<0.05).The T1,T2,and PD values of pleomorphic adenomas and malignant tumors were significantly higher than those of Warthin tumors(P<0.05).The area under the curve(AUC)of the T2 value in differentia-ting pleomorphic adenomas from malignant tumors was 0.794.The AUC for T1 value(0.939)in differentiating Warthin tumors from malignant tumors was significantly higher than that of T2(0.873,P=0.341)and PD(0.927,P=0.891)values,without sta-tistically significant difference.The AUC for T2 value(0.968)in differentiating pleomorphic adenomas from Warthin tumors was significantly higher than that of T1(0.931,P=0.360)and PD(0.876,P=0.120)values,without statistically significant difference.Conclusion Quantitative relaxation parameters based on synthetic MRI technology may contribute to differentiating pleomorphic adenomas,Warthin tumors,and malignant tumors of the parotid gland.

Objective To investigate the value of three-dimensional amide proton transfer(3D APT)imaging and multi-model diffusion weighted imaging(DWI)in evaluating the histological grade of cervical squamous cell carcinoma(CSCC).Methods A total of 54 patients with CSCC at different grades were prospectively included.All subjects underwent pelvic 3D APT and multi-b-value DWI sequences on a 3.0T MR scanner.Two radiologists blindly measured the amide proton transfer(APT)values of all continuous layers of the lesion,the apparent diffusion coefficient(ADC)of the mono-exponential-model of DWI,the ture-diffusion coefficient(D),pseudo-diffusion coefficient(D*),perfusion fraction(f)of intravoxel incoherent motion(IVIM)imaging,and the mean diffusivity(MD)and mean diffusion kurtosis(MK)values of diffusion kurtosis imaging(DKI).The receiver operating characteristic(ROC)curve was used to analyze the efficacy of each parameter in identifying different pathological grades of CSCC.Results The APT mean signal intensity(SImean),APT maximum signal intensity(SImax)and maximum mean diffusion kurtosis(MKmax)values of the high-grade group were statistically higher than those of the low-grade group,and the minimum apparent diffusion coefficient(ADCmin),minimum ture-diffusion coefficient(Dmin),and minimum mean diffusivity(MDmin)values were statistically lower than those of the low-grade group(P＜0.05).The area under the curve(AUC)increased after the combination of APT parameters and DWI parameters,which was obviously higher than that of a single parameter(P＜0.05).Conclusion Both APT and multi-model DWI are helpful to identify the degree of differentiation of CSCC,and the diagnostic value of combining the two is higher.
