Salpingogram (Tubogram): Fallopian Tube X-Ray for Fertility Evaluation

A salpingogram (also tubogram or hysterosalpingogram/HSG) is an X-ray procedure that evaluates fallopian tube patency and uterine cavity shape.

Procedure

• Contrast medium injected through the cervix into the uterus.
• Fluoroscopic images track contrast flow through tubes into the peritoneal cavity.
• Performed outpatient, usually in the follicular phase (days 6–12 of cycle).

Purpose

Identifies tubal blockages, hydrosalpinx, uterine anomalies (septum, fibroids) that may cause infertility or recurrent pregnancy loss.
