What is Doppler Ultrasound?
The Doppler principle has long been used in both NST devices and devices used to listen to the baby's heartbeat. The adaptation of this principle to ultrasound devices has opened new horizons in the field of obstetrics.
The Doppler ultrasonography examination, which allows the assessment of blood flow patterns in the blood vessels of the baby, provides useful information about the well-being of the baby.
The technology called flow color flow mapping ise allows the blood flow to be displayed on the monitor as represented by colors. In this method, the blood flowing through the arteries and veins is represented by different colors.
While these devices initially reflect the image obtained from different angles to the screen after processing with the help of computer software, the advanced devices used today can produce three-dimensional images simultaneously with the examination. Simultaneously, the desired 3-D image is obtained from the moment the probe is placed on the patient's abdomen.
The importance of 3-D ultrasound is to detect some of the anomalies of the baby much more easily. In addition, seeing the babies before the birth of the mother-to-be is helpful in strengthening the psychological bond between them.
Is ultrasound any harm to the baby?
Ultrasonography has been used on pregnant women for more than 40 years. It does not have toxic effects on the developing fetus since ionized radiation such as X-ray is not used in ultrasonography.
Although prolonged exposure to ultrasound waves in the laboratory has been shown to cause slight warming of tissues, many clinical studies have shown that ultrasound has no detrimental effects on humans and animals. Although limited studies have suggested that ultrasonography is associated with low birth weight, left-handedness and hearing impairment, these findings have not been confirmed in many studies with a large number of patients.
The greatest risk associated with ultrasound applications during pregnancy is the risk that some fetal anomalies will be overlooked, especially when investigations are performed by people who do not have sufficient experience. In order to minimize this risk, it is common and effective to have at least one examination performed by another physician throughout the entire pregnancy. 19-21 at our center. detailed ultrasound is performed by a physician trained in perinatology.
