摘　　要：目的探讨输卵管妊娠的MR表现及其临床意义。方法回顾性分析10例经病理证实的输卵管妊娠的手术所见及MRI表现。结果手术见输卵管妊娠破裂6例，4例未破裂。MRI表现：（1）病变位于子宫旁附件区。（2）病变多表现为圆形或椭圆形软组织肿块，边缘清楚或模糊。（3）病灶和盆腔内出血，提示有破裂。（4）增强扫描可见病灶有边缘强化。（5）未破裂输卵管妊娠呈水样信号的小囊状病灶。（6）子宫有轻度增大，宫腔内未见异常信号。结论MR成像能清楚显示输卵管妊娠病灶，当出现上述MR征象并有停经史时应高度怀疑为输卵管妊娠。Objective To evaluate MR findings and clinical significance of tubal pregnancy. Methods Ten patients with tubal pregnancy proved by surgery and pathology undrwent MRI examination because of diagnostic difficulty after ultrasonography, human chorionic gonagotropin (HCG) assessment and clinical evalustion. Clinical data and MRI appearances were reviewed. Results Increase of HCG was found in 8 patients,normal in 2 patients. 6 cases with ruptured for pregnany were found in operaon and 4 cases intact. MRIappearances of tubal pregnancy were as follows: (1) The location of lesion was in parametrial, tubal region, (2)The lesion was round soft tissue mass with clear or unclear margin. (3) Heerogeneous hemorrhagic mass with pehic blood collection could be characteristic MR findings of ruptured tubal pregnancy, the lesions showed hyperintensities on T1WI, T2WI and T2WI with SPIR. (4) Marginal enhancemen with Gd-DTPA was revealed.(5) Watery signal intensity on SE T1wi and TSE T2WI was seen in early, unruptured tubal pregnancy. (6)The uterus could be slightly enlarged, but the signal remained normal. Conclusion MRI can clearly demonstrate the lesions of tubal pregnancy. The MR findings with the history of amenorrhea are strongly suggestive of the diagnosis.
