Different types of fetal ultrasound scans are performed to ensure the healthy progress of the pregnancy. The transvaginal scan during pregnancy is done by inserting a scanning instrument in the vagina. It helps doctors check the reproductive organs of a pregnant woman and assess the fetal health. This procedure is simple and painless and is usually done during the early stages of pregnancy. However, your doctor may advise you to get it done later based on your pregnancy. Read this post for detailed information on transvaginal ultrasound scans, including why and how it is done and how you can prepare for it.
What Is A Transvaginal Scan?
It is a safe and effective, noninvasive diagnostic scan that provides images of the female pelvic area including the bladder, ovaries, fallopian tubes, cervix, and uterus. In pregnant women, the test helps to assess the pregnancy and health of the growing fetus. It measures various parts of the fetus such as the spine, head, and the heart (1) (2). The test is done using a thin and long transducer, which is inserted into the vagina. This instrument is also known as a probe and is covered in latex or plastic sheath. A clear conducting gel is applied to it before the scan. The probe used in the ultrasound consists of a microphone, which sends high frequency sound waves (ultrasound) through the vagina into the pelvic cavity which are then reflected back to the microphone. These sound waves are converted to electrical impulses that produce a moving image on the computer screen.. Some other names of the transvaginal ultrasound include pelvic scan, gynecologic ultrasound, endovaginal ultrasound, transvaginal sonography, and pelvic sonography.
What Does A Transvaginal Ultrasound Show?
The ultrasound shows any changes that happen in the mother’s womb, the ovaries, or the organs surrounding it. In addition to this, it helps to detect any problems related to fetal health so that they can be managed early on. In rare cases, a tissue sample can be taken during the scan for further assessment. In addition to this, a hysterosalpingogram could also be done at the time of the ultrasound to check the inside of the uterus and patency of the fallopian tube (3) (4). The scan also helps (5) (6): The main objective of TVS in pregnancy is to assess fetal health and to detect any complications.
