Accurate diagnosis of ectopic pregnancy is essential in reducing maternal mortality and morbidity. Transvaginal ultrasound (TVUS) is the accepted imaging modality of choice for the diagnosis of ectopic pregnancy (EP).
To assess the effectiveness of transvaginal ultrasound (TVUS) in the detection of EP in consecutive women presenting for ultrasound to a radiology department with a clinical suspicion of EP.
Retrospective analysis of 585 women presenting for TVUS over a 2.5-year period was performed. Women were classified as having a confirmed EP on the basis of surgery and histology. Women with a suspected EP who were treated medically or expectantly were also included.
Eighty-seven women had a confirmed EP and 29 women had a suspected EP. The sensitivity and specificity of ultrasound for the detection of confirmed EP was 88.5% and 96.5% on the initial TVUS and 93.1% and 95.7% with an additional rescan.
TVUS in the radiology setting of a tertiary hospital has excellent diagnostic performance for the detection of EP.
准确诊断异位妊娠对于降低孕产妇死亡率和发病率至关重要。经阴道超声（TVUS）是诊断异位妊娠（EP）公认的首选成像方式。
评估经阴道超声（TVUS）在对临床怀疑为异位妊娠的连续女性进行超声检查时检测异位妊娠的有效性。
对2.5年内接受经阴道超声检查的585名女性进行回顾性分析。根据手术和组织学结果将女性分为确诊为异位妊娠。也纳入了接受药物治疗或期待治疗的疑似异位妊娠女性。
87名女性确诊为异位妊娠，29名女性疑似异位妊娠。初次经阴道超声检查时，超声检测确诊异位妊娠的敏感性和特异性分别为88.5%和96.5%，再次扫描时分别为93.1%和95.7%。
三级医院放射科环境下的经阴道超声在检测异位妊娠方面具有出色的诊断性能。
