2. Transabdominal Pelvic Ultrasound Protocol

Step 3: Obtain View of Ovaries

The ovaries can be difficult to find because of the overlying bowel gas. Having a full bladder can help visualize the ovaries in a transabdominal view since the bladder can be used as an acoustic window. For the most part, transvaginal ultrasound should be used to evaluate the ovaries.

  • With the probe still in the transverse position, rock the tail of the probe to the patient’s left to visualize the right ovary.
  • You can visualize the left ovary using a similar technique (rock the tail of the probe to the patient’s right).
Transabdominal Pelvic Ultrasound Ovary Probe Positioning

An ovary can be identified on ultrasound by the following characteristics:

  • Lateral and/or posterior to the uterus
  • Typically measures 2-3 cm in diameter
  • Less echogenic than surrounding tissue
  • Static (compared to surrounding bowel)
  • Anechoic follicular structures
