In general, you can use either a sagittal or transverse view to identify the ovaries, which are usually located lateral and/or posterior to the uterus (Sohoni 2014).
Tip: If you have trouble viewing the ovary, try directing the endocavitary probe more posteriorly.
An ovary can be identified on transvaginal ultrasound by the following characteristics:
- Posterior and lateral to uterus
- Typically measures 2-3 cm in diameter
- Less echogenic than surrounding tissue
- Static (compared to surrounding bowel)
- Anechoic follicular structures
Step 4: Disinfect Endocavitary Probe
When you complete your transvaginal ultrasound exam it is imperative that you disinfect the probe properly using your hospital approved process.
