Limitations of imaging screening tests in the detection of incomplete uterine septum or arcuate uterine anomaly.

Objectives: To determine the detection rates of hysterosalpingogram (HSG), transvaginal 2D ultrasound (TV 2D US), transvaginal 3D ultrasound (TV 3D US) in diagnosing of incomplete uterine septum (IUS) and significant arcuate uterine anomaly (AUA).

Methods: This retrospective cohort study included patients with infertility or recurrent pregnancy loss (516) that were found to have IUS (317) or significant AUA (199) on diagnostic hysteroscopy (DHS). We compared the detection rate of the various radiological tests in all patients with documented IUS or AUA on DHS.
