Ultrasonography Q & A

What is ultrasonography?

Ultrasonography is another term for an ultrasound, a diagnostic imaging study that uses high-frequency sound waves and their echoes to create images of your internal organs. Dr. Williamson uses ultrasonography to examine your uterus, ovaries, bladder, and other pelvic organs to diagnose medical conditions such as endometriosis and uterine fibroids.

What is sonohysterography?

Sonohysterography is a special type of ultrasound that Dr. Williamson uses to examine the inside of your uterus. During sonohysterography, Dr. Williamson uses a catheter to fill your womb with fluid. The fluid slightly expands your uterus, which helps create more precise images of its interior and lining.

Dr. Williamson uses sonohysterography to diagnose:

  • Fibroids and polyps
  • Scar tissue
  • Abnormal endometrial lining
  • Fallopian tube blockages


Sonohysterography can also reveal if your uterus has an irregular shape, which could interfere with your fertility.

What should I expect during an ultrasonography procedure?

Dr. Williamson gives you instructions on how to prepare for your ultrasound. In most cases, you don’t need to do anything special, although you may need to have a full bladder. Ultrasound procedures are completely painless and usually only take a half hour.

During a regular ultrasonography procedure, you rest on a treatment table and move your clothing to reveal your abdomen. Your ultrasound technician applies a clear gel to your skin, which helps the sound waves travel through your body.

The technician then gently moves a transducer wand over your abdomen. The transducer sends the sound waves through your body and receives the echoes as the waves bounce back from your organs.

The ultrasound equipment and computer convert the sound waves into images that Dr. Williamson can study on a video screen.

The process is similar for sonohysterography, except that your procedure begins with Dr. Williamson inflating your uterus with fluid before starting the ultrasound procedure.

In some cases, Dr. Williamson may need to use a transvaginal ultrasound to get clear images of your reproductive organs. Transvaginal ultrasounds work the same way as external ultrasounds, but your technician inserts a smaller transducer wand into your vagina instead of moving a wand over your abdomen.
