A sonohysterogram is a procedure that combines the use of high-resolution endovaginal ultrasound with the infusion of sterile saline into the uterine/endometrial cavity, creating an enhanced view of the endometrium. This diagnostic tool serves to evaluate polyps, fibroids, endometrial atrophy, endometrial adhesions (or scarring), malignant lesions/masses and congenital defects.
How should I prepare for my exam?
Please follow the instructions given by your healthcare provider.
If possible, please schedule 7-10 days after start of the last menstrual period.
How long will my exam take?
A sonohysterogram typically takes 60 minutes.
What happens during my exam?
You will be positioned on a cushioned table and sterile saline will be injected into the cavity of the uterus, distending or enlarging it. The saline outlines the endometrium (the lining of the uterine cavity) and allows for easy visualization and measurement with ultrasound imaging. Saline and air may also be injected into the uterus so that the radiologist can look for air bubbles passing through the fallopian tubes, which would indicate open or exposed fallopian tubes.
What happens after my exam?
Your images will be interpreted by one of our board-certified radiologists. The findings will be sent to your healthcare provider who will then contact you to discuss the results.
You will be observed for a period of time after the exam.
