What is Ultrasonography?

Ultrasonography is one of the most important and useful diagnostic tool in the field of modern medicine. Being noninvasive, safe and without hazards of radiation, it has gained wide acceptability, as an integral part of basic investigative procedures. The convenience, high portability, rapidity, and accuracy are few of the advantages of ultrasound over the other procedures. In the last two decades, ultrasound has become an essential diagnostic imaging modality in the field of obstetrics and is being extensively used for evaluation of pregnancy. Obstetrical ultrasound enables the clinician to evaluate the development, growth, and wellbeing of the fetus.

Trans-vaginal ultrasonography
Trans-vaginal ultrasound is a test used to look at a woman’s reproductive organs, including the uterus, ovaries, and cervix. This can be very helpful in early pregnancy as it is able to provide a better view.
Uses of Trans-vaginal ultrasonography

  • An abnormal physical exam
  • To check for cysts or fibroids
  • Unexplained vaginal bleeding
  • Pelvic pain
  • An ectopic pregnancy (which occurs when the fetus begins to develop outside of the uterus, usually in the fallopian tubes)
  • Infertility

Your doctor might also recommend a trans-vaginal ultrasound during pregnancy to:

  • Monitor the heartbeat of the fetus
  • Observe the cervix for any changes that could lead to complications such as miscarriage or premature delivery
  • Find the source of any abnormal bleeding
  • Diagnose a possible miscarriage

Trans-vaginal ultrasound method

  • The test takes less than 10 minutes. Lying on your back with your knees bent
  • The transducer is gently inserted (either by the examiner or yourself) into the vagina and rested against the cervix.
  • The examiner rotates the transducer to one side, then the other, to obtain different views of the targeted organs on a viewing monitor.
  • Once clear images are obtained, they are recorded on film or video for later analysis.
  • The test takes less than 10 minutes.
