Transabdominal and Transvaginal ultrasound
Used extensively to assess pelvic organs, to diagnose and manage gynecologic problems including:
- lelomyomas (fibroids)
- ovarian cysts and tumours
- adnexal masses, including ectopic pregnancy.
Having a full bladder for the transabdominal portion of the exam is helpful because sound travels through fluid with less attenuation to better visualize the uterus and ovaries which lies posterior to the bladder.
The transvaginal ultrasound utilizes a higher frequency transducer, which gives a better resolution of the ovaries, uterus and endometrium and adnexa. The exam involves insertion of a transducer into the vagina after emptying your bladder. The tip of the transducer is smaller than the standard speculum used when performing a pap test. A protective cover is places over the transducer, lubricated with a small amount of sterile gel and then inserted into your vagina which allows for better visualization of your pelvic organs. The required images are then acquired at various planes. When the exam is over the sonographer will wipe off the gel and disinfect the transducer.
