Ultrasound is a common diagnostic imaging technique that uses high-frequency sound waves to produce dynamic images (sonograms) of the internal organs and tissues and to examine blood flow.
Obstetric ultrasounds are used to check the size, location, number, and age of the fetus or fetuses. It can also be used to detect fetal movement, breathing, and heartbeat, as well as some types of birth defects.
Types of Tests
An abdominal ultrasound is a type of ultrasound 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.
Thyroid ultrasounds provide insight into whether or not this gland, responsible for regulating metabolism and found in the neck, is functioning properly.
A transvaginal ultrasound is a method of evaluating the genital tract and pelvis area that provides higher quality images than a traditional abdominal ultrasound. It can be safely used during pregnancy and may be ordered to provide a better picture of the fetus.
Testicular ultrasounds help examine the testicles and other scrotal structures.
A carotid ultrasound is a procedure used to assess blood flow through the carotid artery. The ultrasound helps locate and examine obstructions and narrowing of the arteries.
