Published: August 9, 2026Updated: August 16, 2026

A transvaginal ultrasound with Doppler measures blood-flow speed in pelvic blood vessels and records the highest, or peak, velocity measured.

What is this test?

Transvaginal Doppler ultrasound combines an internal pelvic ultrasound with Doppler technology. It evaluates blood flow in the vessels being examined and may record a peak velocity, which is the highest blood-flow speed measured during a heartbeat.

Why might I need this test?

This test may be used to investigate pelvic pain, menstrual or fertility concerns, ovarian or uterine conditions, or blood-flow problems. Your clinician will select it based on your symptoms and the specific blood vessels or organs being evaluated.

How is the test performed?

A trained sonographer places a covered ultrasound probe gently inside the vagina. The probe creates images and uses Doppler to show the direction and speed of blood flow; the peak velocity is then measured from the relevant vessel.

How do I prepare for the test?

Follow the instructions provided by the imaging center. You may be asked to empty your bladder, and the center may advise you about eating, drinking, or taking medications depending on the specific examination.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

An unusually high or low peak blood-flow velocity can indicate altered circulation in the examined pelvic vessel. Depending on the vessel and clinical context, this may be associated with conditions affecting the ovaries, uterus, or pelvic blood vessels. The result must be interpreted with the ultrasound images, symptoms, and other findings by your clinician.

Frequently asked questions

Is this test the same as a routine transvaginal ultrasound?
Not always. A transvaginal ultrasound may include Doppler imaging when blood flow needs to be assessed, as in this test.
Does the test involve radiation?
No. Ultrasound uses sound waves rather than radiation, and Doppler ultrasound does not use ionizing radiation.
Why was I told the test name or code is deprecated?
The laboratory or imaging program may have retired an older name or billing code while continuing to use an updated code for the same examination. Ask the ordering office which current code is being reported.
