Sonography
USG TVS is defined by how it's done, not by why: an ultrasound probe is placed inside the vagina instead of scanning through the abdomen. That closer position gives a clearer, more detailed view of the uterus, ovaries, and, in early pregnancy, the gestational sac, than an abdominal scan alone typically gives. It's commonly used in early pregnancy, when structures are still small and a clearer view genuinely changes what can be seen, and in general gynaecological assessment, when your doctor needs a closer look at the uterus or ovaries than an abdominal scan provides. Your doctor or the centre can walk you through what to expect beforehand.
This scan uses an internal probe to get a closer, clearer view of your uterus and ovaries, or an early pregnancy, than scanning through the abdomen alone typically gives. It's used whenever that closer view specifically changes what your doctor can see and assess.
Most ultrasound scans in this catalogue are defined by what they check. USG TVS is defined by how the scan is done instead: the probe goes inside the vagina rather than staying on the surface of the abdomen.
Placing the probe closer to the uterus and ovaries cuts down the distance sound waves have to travel and avoids interference from the abdominal wall and bowel gas that can blur an abdominal scan. That closer position is why this approach often gives a sharper, more detailed picture of the uterus, ovaries, and, in early pregnancy, the gestational sac.
This approach is common in early pregnancy, when the structures being checked are still too small for an abdominal scan to show clearly, and in general gynaecological assessment, when your doctor needs a closer look at the uterus or ovaries than an abdominal scan gives. It can also be used alongside an abdominal scan in the same visit rather than instead of one.
A probe covered with a protective sheath and gel is gently placed inside the vagina. Most people find it involves some pressure but not pain. Ask your doctor or the centre beforehand if you have specific concerns about the approach.
It's defined by the route rather than the purpose. The probe is placed inside the vagina instead of scanning through the abdomen, giving a closer, clearer view of the uterus and ovaries.
No, though you may feel some pressure as the probe is placed. It's generally not described as painful.
The internal position gives a sharper, closer view of the uterus and ovaries, which matters most in early pregnancy or when an abdominal scan alone doesn't give a clear enough picture.
Yes. It's commonly used in early pregnancy, when structures like the gestational sac are still small enough that a closer view makes a real difference.
This page is general information about the test, not medical advice. Your own report's reference ranges apply — please discuss your results with your doctor.
Yes, the two can be done together in the same visit when your doctor wants both views rather than one in place of the other.
Yes. Like other ultrasound scans, it uses sound waves rather than radiation and has no known harmful effects.
There's no single preparation that applies to every patient. Ask your doctor or the centre what they'd like you to do beforehand.
