To compare the accuracy of transvaginal sonography (TVS) and transabdominal sonography (TAS) in the diagnosis of ectopic pregnancy occurring in the fallopian tubal.
Thirty-eight patients with ectopic pregnancy in the fallopian tube were examined by TAS with moderately filled bladder, followed by reexamination with TVS with the bladder emptied. The manifestations in the 2 imaging examinations were compared.
TVS showed masses in 38, gestations in 23, heart beat in 10, pelvis fluid in 16 and circular blood signal in 25 cases respectively, while TAS identified masses in 30, gestations in 13, heart beat in 5, pelvis fluid in 14 and circular blood flow signal in 13 cases.
TVS may offer an earlier, clearer and more exact diagnosis of ectopic pregnancy in the fallopian tube than TAS is capable of.
比较经阴道超声检查（TVS）和经腹超声检查（TAS）对输卵管异位妊娠的诊断准确性。
对38例输卵管异位妊娠患者，先在膀胱适度充盈时行TAS检查，然后排空膀胱再行TVS复查。比较两种影像学检查的表现。
TVS检查分别显示38例有包块、23例有妊娠囊、10例有心跳、16例有盆腔积液、25例有环状血流信号；TAS检查分别显示30例有包块、13例有妊娠囊、5例有心跳、14例有盆腔积液、13例有环状血流信号。
与TAS相比，TVS对输卵管异位妊娠可能能提供更早、更清晰、更准确的诊断。
