Abstract
Objective To analyze the diagnostic value of dynamic enhanced magnetic resonance imaging combined with apparent diffusion coefficient(ADC)value for endometrial cancer.Methods 60 patients admitted to our hospital from April 2021 to April 2024 who were diagnosed as endometrial cancer by pathological diagnosis were selected and included in the observation group,and 60 patients with benign submucosal leiomyomas of the uterus admitted to our hospital during the same period were selected and included in the control group.Conventional magnetic resonance scanning,dynamic enhanced scanning and diffusion weighted imaging(DWI)were performed on the two groups of patients,and the magnetic resonance imaging findings were analyzed.The rADC values of the obturator muscle,the rADC values of the myometrium,the rADC values of the gluteus maximus and the ADC values were compared between the two groups.The ROC curve was established to analyze the diagnostic efficacy of dynamic enhanced magnetic resonance imaging combined with ADC value for endometrial cancer.Results The MRI results of benign submucosal leiomyomas of the uterus showed that the uterine shape was enlarged,the normal anatomical morphology of the uterus could be found to disappear in T2WI,the myometrium was thickened,and the endometrium could be presented as a low signal on T1WI,with the signal of the lesion higher than that of the normal endometrium,and the DWI showed a high signal,and the ADC map showed a low-signal change.The MRI results of endometrial cancer showed that the shape of the uterus was enlarged to different degrees,the endometrium could present low signal or slightly low signal in T1WI,and the thickness of the endometrium could be found to be more than 12 mm in T2WI,the signal of the foci was higher than that of the normal endometrium,and the signal of the DWI was high,and the ADC map presented low-signal changes.In the observation group,the rADC value of the endosseous muscle,the rADC value of the myometrium,the rADC value of the gluteus maximus muscle and the ADC value were significantly lower than those of the control group(P＜0.05);the ROC curve showed that the AUC of dynamic enhancement magnetic resonance combined with the ADC value in the diagnosis of endometrial carcinoma was 0.762,and the sensitivity and specificity were 82.78％and 91.37％,which were significantly higher than that of its diagnosis alone.Conclusions Dynamic enhanced magnetic resonance imaging combined with ADC value has high diagnostic sensitivity and specificity for endometrial cancer,which is worthy of clinical reference and application.关键词
