What is TVS doppler?
Doppler USG uses the principle known as “doppler effect” according to which there is change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave.(kindly refer to colour doppler obstetric scan for more details)
TVS allows evaluation of female pelvic organs from very close and hence in greater detail.
Doppler ultrasound, sometimes called a duplex study is used to show the speed and direction of blood flow in certain pelvic organs.
Benefits :
Blood flow to the ovary and uterus keeps on changing during the menstrual cycle and their assessment can help in diagnosing certain conditions especially in patients with subfertility.
Blood flow assessment also helps in evaluation in patients with very early pregnancy.
Blood flow is seen in a form of wave, analysis of which may be useful in discriminating benign from malignant uterine masses.
It also helps in the diagnosis of conditions like pelvic thrombophlebitis and ovarian torsion etc.
Is it safe?
Yes. Doppler TVS uses sound waves to produce images and are safe.
