Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce dynamic images (sonograms) of organs, tissues, or blood flow inside the body. Prenatal ultrasound examinations are performed by trained professionals, such as sonographers, radiologists, and obstetricians. The procedure involves using a transducer, which sends a stream of high-frequency sound waves into the body and detects their echoes as they bounce off internal structures. The sound waves are then converted to electric impulses, which are processed to form an image displayed on a computer monitor. It is from these images that videos and portraits are made.
Obstetricians use ultrasound at a very low power level to check the size, location, number, and age of fetuses, the presence of some types of birth defects, fetal movement, breathing, and heartbeat.
The test is done in our Ultrasound room. You will be lying down for the procedure. A clear, water-based conducting gel is applied to the skin over the area being examined to help with the transmission of the sound waves. A handheld probe called a transducer is then moved over the area being examined. You may be asked to change position so that other areas can be examined.
Abdominal ultrasound is an imaging procedure used to examine the internal organs of the abdomen including the liver, gallbladder, spleen, pancreas, and kidneys. The blood vessels to some of these organs can also be evaluated with the use of ultrasound techniques.
The thyroid is a gland located in the neck that regulates metabolism. Ultrasound is a painless method of examining the thyroid. This test involves high-frequency sound waves that are emitted and received by a transducer (a handheld instrument), and the sound waves penetrate the body. The sound waves are arranged into an image seen on a screen, based on the way they bounce off of the various body structures.
Transvaginal ultrasound is a method of imaging the genital tract in women. The ultrasound machine sends out high-frequency sound waves, which bounce off body structures to create a picture.
With the transvaginal technique, the ultrasound transducer (a hand-held probe) is carefully inserted directly into the vagina. It is therefore closer to pelvic structures than with the conventional transabdominal technique (with the probe on the skin of the abdomen), providing superior image quality. This test can be used during pregnancy.
Testicle ultrasound is an imaging procedure to examine the testicles and other scrotal structures. The ultrasound machine sends out high-frequency sound waves, which reflect off scrotal structures to create a picture.
Carotid duplex is an ultrasound procedure performed to assess blood flow through the carotid artery to the brain. High-frequency sound waves are directed from a hand-held transducer probe to the area. These waves “echo” off the arterial structures and produce a 2-dimensional image on a monitor, which will make obstructions or narrowing of the arteries visible.
