Medical ultrasound scan ultrasonography is a non-invasive diagnostic imaging technique that uses high-frequency soundwaves which bounce off the tissues with different reflection properties to create images called sonograms that show the inside of the body. These sound waves are greater than 20 kHz, meaning that the human ear cannot hear them. It can help visualize blood flow in organs, the movements of the walls of the heart, to break up kidney stones, to look at tumors or internal injuries, and much more. It is an irreplaceable tool in the age of modern medicine.

Obstetric ultrasonography , or prenatal ultrasound , is the use of medical ultrasonography in pregnancy , in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus womb. The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the health of the mother, the timing and progress of the pregnancy, and the health and development of the embryo or fetus. The International Society of Ultrasound in Obstetrics and Gynecology ISUOG recommends that pregnant women have routine obstetric ultrasounds between 18 weeks' and 22 weeks' gestational age the anatomy scan in order to confirm pregnancy dating, to measure the fetus so that growth abnormalities can be recognized quickly later in pregnancy, and to assess for congenital malformations and multiple pregnancies twins, etc. Performing an ultrasound at this early stage of pregnancy can more accurately confirm the timing of the pregnancy, and can also assess for multiple fetuses and major congenital abnormalities at an earlier stage. There is no difference, however, in perinatal death or poor outcomes for infants. Below are useful terms on ultrasound: . In normal state, each body tissue type, such as liver, spleen or kidney, has a unique echogenicity.
Ultrasound Scan at 7 Weeks of Pregnancy
Back to Health A to Z. An ultrasound scan, sometimes called a sonogram, is a procedure that uses high-frequency sound waves to create an image of part of the inside of the body. You can't hear these sound waves, but when they bounce off different parts of the body, they create "echoes" that are picked up by the probe and turned into a moving image. Before having some types of ultrasound scan, you may be asked to follow certain instructions to help improve the quality of the images produced.
