OBJECTIVE: To determine the role of @entity7994 in the early diagnosis of @entity7207 (EP). METHODS: Clinical and @entity7994 features of 27 cases of @entity7207 were reviewed. RESULTS: A thick-walled @entity8597 ( @entity8597 )-like structure was demonstrated lateral to the uterus in all cases. On T2-weighted images, the thick wall typically exhibited 3 discrete rings in 22 cases (81  %), among which 17 cases (63  %) displayed small vessels and 6 cases (33  %) exhibited small areas of fresh @entity548 inside the thick wall. The contents demonstrated non-specific liquid in 26  %, papillary solid components in 56  %, and fresh blood or fluid-fluid level in 19  % of the cases. Dilatation of the affected fallopian tube associated with hematosalpinx was demonstrated in 18 cases (67  %) and marked enhancement of the tubal wall was observed in 22 cases (81  %). No correlation was found between the size of the @entity8597 and the estimated gestational age (r   =   0.056). CONCLUSION: @entity7994 plays an important role in the early diagnosis and management of @entity7207 . The characteristic @entity7994 features include a @entity8597 -like structure with a "three rings" appearance on T2-weighted images, presence of solid components in the sac, dilatation of the affected fallopian tube with hematosalpinx, and tubal wall enhancement. KEY POINTS:     MR imaging has served as a problem-solving procedure in ectopic pregnancy.     MR imaging features can be criteria for early diagnosis of @entity7207 .     Detailed assessment of ectopic implantation is necessary for management decision-making.
