[Abstract] Objective To explore the structural changes of uterus caused by endometrial fibrosis on magnetic resonance imaging (MRI). Materials andMethods This study prospectively enrolled fifty-three infertility patients with endometrial fibrosis confirmed by hysteroscopic and thirty-four healthy women with childbearing age. All participants received conventional MRI during periovulation phase. Uterine anatomical parameters including endometrial thickness (EMT), length of uterine cavity (LUC) and junctional zone thickness (JZT) were measured and statistically analyzed. A multivariable model using the binary logistic regression analysis was built to predict endometrial fibrosis with indicators that were statistically significant for univariate analysis. AUCs of parameters were compared using Z‐test.Results EMT of patients (7.46±1.14 mm) was significantly thinner than that of healthy women (11.09±2.26 mm) (P<0.01). LUC of patients (30.79±4.15 mm) was significantly shorter than that of healthy women (36.50±3.25 mm) (P<0.01). JZT of patients (6.39±1.80 mm) was significantly thicker than that of healthy women (3.98±1.16 mm) (P<0.01). EMT, LUC, JZT and the multivariable model revealed good performance in diagnosing endometrial fibrosis with AUCs of 0.917, 0.853, 0.883 and 0.974. The AUC of the multivariate model was significantly higher than that of EMT, LUC and JZT, respectively (all P<0.05).Conclusions MRI can show the structural changes of uterus for patients with endometrial fibrosis visually and dynamically, which makes it a suitable method for clinical follow-up and helping clinicians to grasp the changes of endometrial fibrosis. |
