• Sonography

    Sonography, or Sonohysterography, is a procedure to look at the inside of the uterus. It’s a safe, painless test that uses sound waves and a computer to create images. It does not use radiation.

    The uterus (womb) is the organ where a baby grows during pregnancy. The bottom of the uterus is called the cervix. This is the opening into the uterus. The cervix sits at the top of the vagina.

    During sonohysterography, you’ll be awake and lying down with your knees bent. A slim wand called an ultrasound transducer is placed in your vagina. This wand is covered with a disposable sheath and coated with a special gel.

    Your healthcare provider will then insert a thin, flexible tube (catheter) into your cervix. A salty fluid called saline is sent through the catheter into your uterus. At the same time, the transducer sends high-frequency sound waves through the gel and into your body. The echoes from these sound waves can create a real-time image of the inside of your uterus. This can show the structure of your uterus. The saline fluid helps the ultrasound form an image with sharper detail. Your healthcare provider can use this information to diagnose a number of different health conditions.

    In some cases, the procedure may be done without saline. For example, it wouldn’t be used during pregnancy.

    Doppler ultrasound may be used at the same time, with the same transducer. This can give information about how blood is flowing through the vessels in your uterus.
