Exam Explanation

Hysterosonography also called Sonohysterography or Saline Infusion Sonography, is a minimally invasive ultrasound exam that provides images of the inside of the uterus to help diagnose the cause of abnormal vaginal bleeding.

Exam Preparation

You should inform your doctor or technologist of any medications being taken and if you have any allergies. You must inform the doctor if you are or might be pregnant. The exam is best performed between days seven and ten of your cycle (if you are pre-menopausal) to minimize the chance that you have ovulated or are already pregnant. This procedure should not be performed if you are pregnant and/or if you have an active inflammatory condition. Unlike hysterosalpingogram (or HSG) this test will not determine if the fallopian tubes are open or blocked.

During the Exam

The procedure is like a gynecological exam. You will be asked to remove your clothes below the waist and change into a gown. You may wish to wear a two-piece outfit that day. You will be asked to empty your bladder. You will lie on your back on the exam table. A transducer is inserted into your vagina to view your uterus and ovaries. A catheter is then inserted into the cervix, and a sterile saline solution is injected into the catheter. Ultrasound images are taken during the injection, allowing the evaluation of the uterine lining. This is approximately a 30 minute exam.
