![]() A transrectal ultrasound is sometimes used in the diagnosis of prostate conditions.In a transvaginal ultrasound, a transducer wand is placed in a woman’s vagina to get better images of their uterus and ovaries.Sometimes, however, doctors and technicians can get a better diagnostic image by inserting a special transducer into one of the body's natural openings: Most ultrasounds are done using a transducer on the surface of the skin. Ultrasounds sometimes are used to detect and treat soft-tissue injuries. Ultrasound imaging can help doctors during procedures such as needle biopsies, which require the doctor to remove tissue from a very precise area inside the body for testing in a lab. Ultrasounds do have some diagnostic limitations, however sound waves do not transmit well through dense bone or parts of the body that may hold air or gas, such as the bowel. Doctors employ ultrasound imaging in diagnosing a wide variety of conditions affecting the organs and soft tissues of the body, including the heart and blood vessels, liver, gallbladder, spleen, pancreas, kidneys, bladder, uterus, ovaries, eyes, thyroid, and testicles. And later in pregnancy, doctors can even use ultrasounds to estimate how large a baby is just before delivery.ĭiagnostics.

Ultrasound imaging has many uses in medicine, from confirming and dating a pregnancy to diagnosing certain conditions and guiding doctors through precise medical procedures. This technology can help diagnose and treat certain conditions. Then a radiologist or your doctor will interpret the ultrasound images. Sonogram definition how to#Ultrasound technicians, or sonographers, have special training in how to perform the test. This information is relayed in real time to produce images on a computer screen. An instrument called a transducer emits high-frequency sound, inaudible to human ears, and then records the echoes as the sound waves bounce back to determine the size, shape, and consistency of soft tissues and organs. Ultrasound, also called sonography, uses sound waves to develop ultrasound images of what's going on inside the body. But while fetal imaging is one of the most common uses of ultrasounds, this diagnostic tool actually has many applications. Many people who hear the term " ultrasound" likely picture a pregnant woman in their doctor's office getting a sneak peek of the baby growing inside her womb - perhaps even finding out whether they should paint the nursery pink or blue. ![]()
