Ultrasounds, sometimes referred to as sonograms, are a medical test which uses high frequency sound waves to produce a picture of the organs in the body. The sonogram is the diagnostic medical image created using ultrasound echo or sonographic equipment.
How does a standard ultrasound and a 4D ultrasound differ and compare?
Image Production. For standard ultrasounds, these are routinely prescribed to produce an image of the organs or fetus, in cases of pregnancy. A 4D ultrasound uses a special sonogram machine and takes images from a few different angles, which reveal more detailed images of the organs or fetus, such as facial features. The movements made by the baby during the procedure can be captured. What a standard ultrasound only provides is a two-dimensional image of the fetus. They are usually ordered in pregnancy for a variety of reasons, such as evaluating development of the baby, determining gestational age and identifying any abnormalities. It takes a trained sonographer or doctor to identify features and body parts because the standard ultrasound only produces a picture of the fetus.
Image Indications. Occasionally, a two-dimensional ultrasound may indicate a medical problem and a more sophisticated 4D ultrasound is needed to confirm an abnormality. For many pregnant women, there is no medical need for a 4D ultrasound, but some moms-to-be want to get a better look at their babies. The baby should usually be big enough where features can be seen clearly, so for clinics that perform a 4D ultrasound, highly recommends that the test is performed after twenty-five weeks gestation.
Image Ultrasound Procedure. Usually, a standard ultrasounds is ordered by a physician to be performed at a clinic, doctor’s office or at an ultrasound imaging center. 4D ultrasounds do not require a doctor’s order and are often done at a private ultrasound business, which specializes in keepsake 4D ultrasounds. The procedure takes about twenty minutes to complete. After a conductive gel is applied to the abdomen, the procedure is done by gliding a transducer over the pregnant women’s abdomen. A monitor is within view, allowing the woman to view the fetus and watch as the ultrasound is completed.
Image Production Concerns. It has not yet been proven that the energy level used in 4D ultrasounds may be higher. This has been an issue as to the safety and vulnerability of the women subjected to the ultrasound procedure. Because 4D machines create a higher quality image, many people or pregnant women subject themselves to ultrasound especially if they want to assure themselves of the condition of their organs or their baby. For women who do want a keepsake photo and opt for a 4D ultrasound, it’s important to make sure that the technician performing the test is a licensed sonographer. Women should consider talking to their doctor regarding any safety concerns prior to the procedure.
