Ultrasound uses the reflections of high-frequency sound waves to construct images of internal organs. A pelvic ultrasound allows a sonographer to visualize and measure a patient’s uterus, endometrial lining, ovaries and other pelvic structures. Pelvic ultrasounds are typically performed transvaginally in the clinic setting. A pelvic ultrasound may be ordered for many reasons. The most common indications for a pelvic ultrasound include abnormal uterine bleeding, pelvic pain, or checking the placement of an IUD.
A sonohysterogram may be ordered to better assess the lining of the uterus due to abnormal uterine bleeding or infertility. The sonographer will begin with a transvaginal pelvic ultrasound to obtain measurements and images of the pelvic structures, including the patient’s uterus, endometrial lining, and ovaries.
To better image the lining of the uterus, saline is introduced into the uterus. To do this, a member of our advanced practice provider team will assist the sonographer by placing a speculum and passing a small catheter through the cervix and into the uterus. Once the catheter is in place, a small amount of saline is pushed through the catheter to enhance the uterine cavity. During the fluid installation, the sonographer captures images and short video clips for interpretation. The patient may experience some cramping, but this procedure is usually well tolerated.
