ABSTRACT
Objective To evaluate the changes of endometrial microcirculation between pre-and postmenopause with magnetic resonance dynamic contrast-enhanced perfusion weighted imaging (MR DCE-PWI)and intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI).Methods Thirty-three patients with normal endometrium (premenopause in 21 and postmenopause in 12)confirmed by pathology underwent DCE-PWI,IVIM-DWI and conventional MRI.Quantitative parameters of DCE-PWI and IVIM-DWI in the endometrium were analyzed and compared between pre-and postmenopause groups.Results The DCE-PWI parameters were significantly higher in premenopause group than those in postmenopause one with significant differences in Ktrans (0.161±0.081)min-1 vs (0.097±0.054)min-1 , Kep (0.285±0.145)min-1 vs (0.184±0.119)min-1 and IAUC60 (20.854±10.695)mmol·kg-1 ·s vs (10.481±6.253)mmol·kg-1 ·s. No significant differences were found between the two groups in IVIM-DWI parameters including D,D* and f values.Conclusion DCE-PWI,rather than IVIM-DWI,can be used to quantitatively evaluate the changes of endometrial microcirculation between pre-and postmenopause.
