Pregnancy Sonograms

During pregnancy sonography is a medical procedure or technique in which high frequency ultrasound waves are used to scan the abdominal and pelvic region of the future mother’s body. This examination creates a picture of the baby growing inside the woman’s uterus. Sonograms and ultrasound are two words which used interchangeably and you can expect to have two or three ultrasound examinations during a pregnancy to monitor the growth of the fetus, to determine gender and to diagnose abnormalities..

Types Of Sonograms or Ultrasounds:

There are seven frequently used types of ultrasound exams. The basic process behind all of them is the same but the procedure is different in every case. These are:

Standard Ultrasound:

This is the traditional ultrasound, in which a transducer is passed over the abdomen in order to produce 2-D images of the developing fetus inside the mother’s womb.

Transvaginal Scans:

This is a specially designed sonogram in which the probe is placed inside the vagina to generate the images of the growing fetus. This technique is mostly used in the early stages of the pregnancy or in women with obesity.


Advanced Ultrasound:

This is an advanced form of the standard ultrasound in which suspected problems can be targeted with the help of sophisticated medical equipment such as testing for Down syndrome.

Doppler Fetal Monitor:

This is a hand-held monitor which can detect the hear beat of a fetus. The information is the same as that of a fetal stethoscope, but it has the advantage that the electronic audio output can be heard by the future parents.

3D Ultrasound:

In this ultrasound 3D images of the growing fetus are created when the sound waves are sent at different angles rather than simply being sent straight up and down as in 2D ultrasound. The sound waves are processed by complex software to reconstruct an image of the fetus in 3D.

4D or Dynamic 3D Ultrasound:

In this type of ultrasound the baby is seen in a 3-dimensional view, but the future parents can also follow the movement of the baby’s body parts, making it 4 dimensional. Parents often find this kind of ultrasound to be very moving as they can track baby’s growth and see what he or she looks like before the actual birth.

Fetal Echocardiography:

This is the process by which ultrasound waves are used to assess and measure the anatomy and functioning of the heart of the growing fetus. It also used to diagnose or estimate the risk of any suspected congenital heart conditions.
