Unlike x-rays which uses radiation in order to be able to image body tissues, sonogram does not involve the use of radiation. The radiation that is produced by x-ray is usually very harmful and overexposure to it can lead to cancer and other medical conditions. That is why it cannot be used to image fetuses during pregnancy. As such, sonogram is the only safe option left.
There are different reasons as to why people require to undergo ultrasound scans. For example, this technique is used to detect wide ranges of growths in parts of the body like the head, breasts, necks, legs, arms, abdomens, and groins. This technique can be used to differentiate a cyst from a solid tumor. Cysts are sacks of tissues in the body with fluid in them.
It can also be used in telling whether an organ has a problem or not. For example, this technique can be used to tell if the heart has wrongly shaped areas or is abnormally sized. Tumors in the chest, belly, hip and tiny ones in the gallbladder can also be detected using sonogram.as already mentioned, physicians use it as a guider while performing surgical procedures.
Several kinds of ultrasounds exist, including 4D, 3d, and 2D. The 2D ultrasonography is the type of ultrasound that is used in hospitals most commonly. This type of ultrasound is used in producing 2D images for the interpretation to be done by a radiologist. The two-dimensional sonogram has been majorly improved by the three-dimensional ultrasonography. The 3D ultrasonography produces 3D images that provide more detailed images that can be understood more easily.
Four-dimensional ultrasonography is the latest technology in this field. This type of sonography is capable of producing a 3D video of body tissue that is observed during observation. For instance, a pregnant woman is able to see the movement of their baby in their womb. Also, someone is able to see cardio activity. The videos have even more detail and are simpler to understand compared to 3D images.
Sonogram is also categorized based on the type of body tissue that it is used for observing in the body. In this group, there is color Doppler ultrasonography and Doppler ultrasound. Doppler ultrasonography is used in observing blood movement and heart activity in the body. The doctor can detect any issue with the flow of blood in heart and heart beats.
On the other side, the direction in which blood is flowing in the body is observed using a color Doppler ultrasonography. The direction in which blood is flowing to tumors, neck, head, organs, and similar growths is what is monitored in this case. Doing this assists in foretelling chances of a person having a stroke.
