Trans -Vaginal Scan (TVS)

A transvaginal ultrasound, or endovaginal ultrasound, is a safe and straightforward procedure that doctors use to examine the internal organs in the female pelvic region.An ultrasound uses high-frequency sound waves to produce detailed images of internal organs.Unlike X-rays, ultrasound scanning techniques do not use radiation, which means that they have no harmful side effects and are very safe. A transvaginal ultrasound can check for ovarian cysts, ovarian tumors, fibroids, and polyps. When most people hear the term ultrasound, they will picture a transabdominal ultrasound, in which doctors pass a device called a transducer over the surface of the skin to obtain internal images.
Although a transabdominal ultrasound can provide information about the abdominal organs, this procedure does not obtain detailed images of the organs in the pelvic region. Some symptoms and medical conditions, such as endometriosis, require images of a higher quality than it is possible to achieve using a transabdominal ultrasound.
Unlike transabdominal ultrasounds, a transvaginal ultrasound is an internal examination. The procedure involves the insertion of the transducer into the vagina to produce incredibly detailed images of the organs in the pelvic region.

It may be necessary to use a transvaginal ultrasound to examine the following internal organs:
vagina
cervix
uterus
fallopian tubes
ovaries
urinary bladder

Transvaginal ultrasounds are also useful to check for:
ovarian cysts or tumors
fibroids
Polyps
Doctors may recommend that people have a transvaginal ultrasound for a variety of reasons. For example, the procedure might be necessary for someone who is experiencing the following signs and symptoms:

• pelvic pain
  unexplained vaginal bleeding
  infertility
• abnormal results from a pelvic or abdominal exam

Doctors may also recommend that some pregnant women have a transvaginal ultrasound as it can be helpful for:

checking the heartbeat of the fetus
confirming the date of pregnancy
assessing the condition of the placenta
checking for ectopic pregnancy monitoring pregnancies with a higher risk of miscarriage.
