The majority of ectopic pregnancies can be diagnosed on transvaginal scan before treatment. Diagnosis should be based on positive visualization of an ectopic pregnancy rather the inability to visualize an intrauterine pregnancy. The majority of ectopic pregnancies will be visible on the initial transvaginal scan performed. Those who do not have their ectopic pregnancies visualized on the first examination will be initially classified as having a pregnancy of unknown location. They will then need follow-up until a diagnosis of ectopic pregnancy is confirmed. This review discusses the use of ultrasound in the diagnosis of ectopic pregnancy and the specific criteria for diagnosis of the different types of ectopic pregnancy.
大多数异位妊娠在治疗前可通过经阴道超声检查诊断。诊断应基于异位妊娠的阳性可视化，而不是无法可视化宫内妊娠。大多数异位妊娠在首次进行经阴道超声检查时即可看到。那些在首次检查中未发现异位妊娠的患者最初将被归类为妊娠位置不明。然后他们需要进行随访，直到异位妊娠的诊断得到证实。本综述讨论了超声在异位妊娠诊断中的应用以及不同类型异位妊娠的具体诊断标准。
