- Abstract:
- Abstract: Objective To explore the clinical value of Siemens 3.0T magnetic resonance (MR) three-dimensional liver volume accelerated acquisition (3D LAVA) dynamic contrast-enhanced diagnosis in endometrial carcinoma staging. Methods 97 patients diagnosed as endometrial cancer stage I and II by pathological examination and admitted to the First Affiliated Hospital of PLA Military Medical University from March 2018 to July 2019 were sampled for the study. 56 patients were examined by using 3D LAVA dynamic contrast-enhanced T1WI, and other 41 patients were examined by diffusion-weighted imaging (DWI). Results (1) The diagnosis accuracy of stage I endometrial carcinoma with 3D LAVA contrast-enhanced examination was significantly higher than that of T2WI. Between the two examination modalities, there was no significant differences in the staging accuracy of stage I and II endometrial carcinoma (P>0.05). (2) After pairwise comparison, some statistically significant differences of the mean ADC values in different pathological grades of endometrial carcinoma was found (P<0.01). Conclusion The accuracy of 3D LAVA dynamic contrast-enhanced examination is higher in diagnosis of stage I and II of endometrial carcinoma, and the ADC value is negatively correlated with the pathological grade ADC value can be used to distinguish the pathological stage and criteria of endometrial carcinoma 3D LAVA dynamic contrast-enhanced examination combined with DWI can reduce the misjudgment rate of pathological staging examination of endometrial carcinoma, and improve the accuracy to select the best treatment.
