概要	Purpose:To evaluate preoperative magnetic resonance (MR) imaging features of bleeding and non-bleeding ectopic pregnancy (EP) by comparison with surgical findings.Methods:Eighteen suspected EP cases underwent preoperative MR imaging. We classified 8 cases as the bleeding group and 7 cases as the non-bleeding group with or without intra-abdominal bleeding and/or hematoma at the site of EP, and compared, retrospectively, gestational sac (GS)-like structure, particularly the peripheral area of the GS via MR analysis. Excluded were 3 cases that were insufficient for assessing extrauterine GS-like structure: ruptured tubal pregnancy and uterine horn pregnancy.Results:GS-like structures were typically observed as low intensity on T1-weighted image (T1WI) and as high intensity on T2-weighted image (T2WI). In non-bleeding cases, most peripheral areas of the GS were of intermediate intensity on T1WI and high intensity on T2WI. Most bleeding cases were of high intensity on T1WI and low to high intensity on T2WI. Furthermore, the peripheral area of the GS was of higher intensity on T1WI with fat suppression than on T1WI.Conclusions:It is clear that MR imaging is effective for diagnosis of cases of suspected EP. EP conditions may be predicted by signal intensity of the peripheral area of the GS via MR analysis.
