Abstract:
Objective To observe the value of combined synthetic MRI and multiplexed sensitivity encoding diffusion weighted imaging(MUSE-DWI)for differentiating benign and malignant endometrial lesions.Methods Data of 112 patients with benign or malignant endometrial lesion confirmed by pathology were retrospectively analyzed.According to pathologic diagnosis,the patients were divided into malignant group(n=72)and benign group(n=40).Synthetic MRI and MUSE-DWI quantitative parameters,including T1,T2,proton density(PD)and apparent diffusion coefficient(ADC)of all lesions were acquired.The clinical data as well as ADC,T1,T2 and PD values of lesions were compared between groups,and those being significantly different between groups were included in univariate and multivariate logistic regression.Then the univariate and combined models were established for differentiating benign and malignant endometrial lesions.The receiver operating characteristic curves were drawn,and areas under the curves(AUC)were calculated to evaluated the diagnostic efficacy of the models,which were compared with DeLong test.Results Patients'age in malignant group were higher than that in benign group(P<0.05).The length of the maximum diameter was larger,ADC,T2 and PD values were lower in malignant lesions than those in benign ones(all P<0.05),while no significant difference of T1 value was found between groups(P=0.074).The AUC of ADC univariate model was 0.966,and there was no significant difference in AUC(0.970)between the combined ADC+T2+PD model(adjusted P>0.05),but both higher than AUC of T2 univariate model(0.618),PD univariate model(0.664)and the combined T2+PD model(0.668)(all adjusted P<0.05).Conclusion ADC univariate model and combined model with other parameters of combined synthetic MRI and MUSE-DWI could be used to effectively differentiate benign and malignant endometrial lesions.
