Transvaginal ultrasound is one of the most commonly performed imaging tests, which is based on the reflection of uneven waves from tissues of varying densities. Transvaginal ultrasound can be used to evaluate the cervix, uterus, fallopian tubes, and ovaries. Your doctor may also order a transvaginal ultrasound to confirm or monitor your pregnancy. This test has no known side effects.
What is the difference between abdominal (transabdominal) and transvaginal ultrasound?
During a transvaginal ultrasound, a narrow ultrasound probe is inserted into the vagina, which transmits and records images of the pelvic cavity on the ultrasound screen. This process differs from traditional abdominal (transabdominal) ultrasound, where the doctor evaluates the pelvic cavity with an ultrasound probe through the abdominal wall and records the images. Transvaginal ultrasound provides a more detailed image of the organs and soft tissues in the pelvic cavity than abdominal (transabdominal) ultrasound.
When is transvaginal ultrasound needed?
Your doctor may recommend this test if you have pelvic pain or abnormal bleeding. Transvaginal ultrasound can provide more information about changes found during a pelvic exam, which can help with diagnosis. This ultrasound can also be used to monitor your pregnancy.
Transvaginal ultrasound allows your doctor to detect:
- Cysts;
- Tumors;
- Fibroids;
- Polyps;
- Signs of pelvic infection;
- Signs of cancer;
- Signs of ectopic pregnancy or miscarriage;
- Possible causes of fertility problems;
- Whether an intrauterine device is in the correct position.
During pregnancy, especially in the first trimester (weeks 1 to 12), your doctor may order a transvaginal ultrasound to:
- Confirm pregnancy;
- Monitor the baby's heartbeat;
- Identify warning signs of miscarriage or premature birth;
- Identify conditions that will affect your pregnancy plan.
How to prepare for a transvaginal ultrasound?
No special preparation is required for this test. The procedure is quick and relatively painless, and the risk of side effects is low.
What happens during a transvaginal ultrasound?
During a transvaginal ultrasound, you will need to undress to the waist and lie down on the examination table. During the ultrasound, a narrow ultrasound probe is inserted into the vagina, which transmits and records images of the pelvic cavity on the ultrasound screen. During the examination, you may be asked to hold your breath or change your position slightly. If any changes are found, the doctor may save the images and print them out if necessary. Transvaginal ultrasound usually takes about 15-30 minutes.
What happens after a transvaginal ultrasound?
After performing a transvaginal ultrasound, the doctor will review and interpret the images, and all information will be stored on the E. health portal. After evaluating the transvaginal ultrasound data, the doctor will inform you whether you need further tests, procedures, or treatment.
When will you find out the results of the ultrasound?
You should receive the results of the transvaginal ultrasound at the end of your visit.
Are there any risks or restrictions associated with transvaginal ultrasound?
Transvaginal ultrasound is based on the reflection of uneven waves from tissues of varying densities, so there is no radiation exposure. This test is painless and safe for you and your baby if you are pregnant. After transvaginal ultrasound, you may experience slight vaginal discharge from the gel used during the procedure, which should disappear after 24 hours.
