What's the difference between a pelvic ultrasound and a transvaginal ultrasound?

What's the difference between a pelvic ultrasound and a transvaginal ultrasound?

Nearly same...: There are two ways to image the pelvic organs. One is by transabdominal route (transducer in placed on the skin of lower abdomen with a distended urinary bladder); and the other is transvaginal ultrasound where the transducer is placed inside the vagina to assess pelvic organs. Transvaginal ultrasound means just that; whereas, pelvic ultrasound includes both transabdominal and transvaginal US. ...Read more

Sonogram (Definition)

The sonogram is a test that looks at body organs with no radiation. It uses sound waves and can give us a 2 dimensional view of organs such as the kidney, liver, heart, and lungs. It can define spaces that are either solid or full of fluid. I can also guide large needles into an organ or near the spine, and can help define the area being cut open. Its a ...Read more

What's hiding my ovaries on a pelvic ultrasound? Can be seen on transvaginal ultrasound instead.

What's hiding my ovaries on a pelvic ultrasound? Can be seen on transvaginal ultrasound instead.

Normal variation: The position of the ovaries varies quite a bit from women to women within the pelvis. Secondly, gas within adjacent bowel loops will distort ultrasound images and 'hide' anything behind that loop. Thus looking from a different angle ie transvaginally, we can find the ovaries that we can see on the transabdominal portion of a scan. ...Read more

Would an pelvic ultrasound, transvaginal ultrasound or cat scan show up a miscarriage?

Ultrasound: A combination of ultrasound (either transabdominal or transvaginal), B-hcg levels, and clinical information are used to diagnose a miscarriage. CT is not used because of its ionizing radiation. ...Read more

Can a transvaginal ultrasound and/or pelvic ultrasound show enlarged lymph nodes around the ovary?

Can a transvaginal ultrasound and/or pelvic ultrasound show enlarged lymph nodes around the ovary?

Yes,: but not reliably. Regional bowel gas can obscure pelvic lymph nodes. Also the position of the ovaries is variable, and they may not be situated next to internal iliac nodal chains. So not seeing enlarged lymph nodes on a pelvic sonogram is not sufficient to exclude them. CT or MRI is much better. ...Read more

Is a pelvic ultrasound as good as a transvaginal u/s at measuring size of ovaries? Are they both accurate?

Possibly equal: It really all depends on how well the ovaries are seen. If the bladder is full and the ovaries are well demonstrated transabdominally then measurements will be as accurate. Transvaginal ultrasound usually provides a more detailed look at the ovaries because the transducer is right next to them. However, sometimes the ovaries are hard to find transvaginally. Each patient is different. ...Read more

Does a pelvic transvaginal ultrasound hurt?

Does a pelvic transvaginal ultrasound hurt?

No: A transvaginal ultrasound is done by inserting an ultrasound probe into the vagina to better evaluate the pelvic organs. Lubrication is applied to the top of the probe to ease insertion. An ultrasound should not be painful. Some women describe a "pressure" sensation but pain should not be experienced. ...Read more

What does it mean if fluid was found in a transvaginal pelvic ultrasound?

It depends: There is a small amount of normal fluid in the pelvis that is often seen on ultrasound. The answer to your question depends on how much fluid, what kind of fluid (what it looks like on us) and where the fluid is. ...Read more

Few things: Sometimes the exam can be painful just because it is an uncomfortable procedure other times because there is an abnormality they are pressing on. The free fluid depends on how much. A tiny amount is normal in females. ...Read more

Can anyone tell me if the pelvic transvaginal ultrasound hurts like a pap?

Transvaginal Ultrasound (Definition)

An ultrasound is an imaging study in which a probe emits and receives sound waves which rebound off of internal organs in order to visualize them. For a transvaginal ultrasound a specially designed probe is lubricated and placed into the vagina in order to better ...Read more

Pelvic Ultrasound (Definition)

This is an ultrasound test to examine the organs of the pelvis, typically using either a trans-abdominal or trans-vaginal approach, depending on what is suspected, such as ovarian ...Read more
