Ultrasound (Sonography) uses high-frequency sound waves; these waves are produced and transmitted to the body by a device placed on the abdomen. A softener gel is applied to the body for a more complete wave transfer to the body. The waves pass through the tissues after entering the body and travel from one organ to another and then are bounced off to the body surface. Ultrasound device receives these waves which are used to take images of internal organs. Movement observation is also possible in ultrasound, so fetal movements or its internal organs can be detected and examined. In weeks 5 to 6 of pregnancy, fetal heart rate is visible as well. Pregnancy ultrasound is used to diagnose the health of the fetus in the mother’s uterus and is normally performed four times as recommended by a gynecologist. All these measurements are carried out to determine the exact age of the fetus and the risk of disease which must be reported by an accurate ultrasound. According to specialists, women are better to have an ultrasound of the uterus and ovaries prior to planning to conceive to get informed about their fertility status. Ultrasound helps the physician to know about the health of the uterus (in terms of size or presence of abnormalities), the presence of apolipo fibroids or ovarian cyst, and many other uterine problems; however, in case of the need for treatment and follow up measures, the patient receives necessary instructions from her doctor.
