[Abstract] Objective: To investigate the diagnostic ability of the phase map of enhanced T2* weighted angiography (ESWAN) in diagnosis of ovarian endometrial cyst.Materials and Methods: This study was approved by the ethics committee of our hospital. A retrospective analysis was performed on 68 cases (80 lesions) pathologically-proven ovarian cystic lesions with pelvic MRI examination (T1WI, T2WI, LAVA and ESWAN sequence). Group A was endometrial cyst (n=42), Group B was ovary pyosalpinx and hydrosalpinx (n=14), Group C were other ovarian cystic lesions (n=24). The morphological characteristics were observed whether there are rings hyperintense outside and hypointense inside and hemorrhagic introtumoral susceptibility signal intensity (ITSS) in the phase image. The above characteristics were compared by Chi-square test or the Fisher exact probabilities. The Logistic regression was used to analyze the combination diagnostic efficacy. The diagnostic efficacy was compared by ROC curve and Wilcoxon test.Results: The lesions with the ring that hyperintense outside and hypointense inside or with hemorrhagic ITSS along the wall in phase image of group A were more than that in group B and C (P<0.001), and there was no difference between group B and C (P value were 0.319 and 0.240 ). Then the best combination were lesion with the ring that hyperintense outside and hypointense and hemorrhagic ITSS inside wall in the phase image (AUC was 0.960).Conclusios: The Combination of observing the ring hyperintense outside and hypointense inside and hemorrhagic ITSS in phase image was best in diagnosing ovarian endometrial cysts.
