When Is the First Ultrasound Done During Pregnancy? An ultrasound is a procedure that uses high frequency sound waves to scan the pelvic cavity and abdomen of a woman, and then creates a sonogram (a picture) of the placenta and the baby. The terms sonogram and ultrasound are technically very different. However, the two are used interchangeably.n ultrasound is a procedure that uses high frequency sound waves to scan the pelvic cavity and abdomen of a woman, and then creates a sonogram (a picture) of the placenta and the baby.

Ultrasound Department Ultrasound Department. Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce 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.

- An ultrasound scan is a painless test that uses sound waves to create images of organs and structures inside your body. It is a very commonly used test. As it uses sound waves and not radiation, it is thought to be harmless.

Ultrasound For the most part, ultrasound is considered a painless, non-invasive diagnostic tool. The procedure usually takes from 30 minutes to an hour. Most ultrasound scans can be performed with the transducer placed atop the skin, with the sound waves aimed at the organ or body part being tested. The patient is usually placed in a comfortable position that provides the ultrasound technician (sonographer) access to the part of the body being tested.

- Abdominal ultrasound is done to: 1  Find the cause of abdominal pain. 2  Find, measure, or monitor an aneurysm in the aorta. 3  An aneurysm may cause a large, pulsing lump in the abdomen.4  Check the size, shape, and position of the liver. Also, these tests may be done if the abdominal ultrasound is normal but abdominal pain persists. 2  Computed Tomography (CT) Scan of the Body. 3  Magnetic Resonance Imaging (MRI) of the Abdomen. 4  A pelvic ultrasound will be used to produce a picture of the lower abdominal (pelvic) organs and other structures inside the pelvis.

What Does an Ultrasound Technician Do? Ultrasound relies on sound waves to produce images of internal organs, soft tissue, and blood vessels, as well as to observe developing fetuses in the womb. Since it is non-invasive and does not use radiation, it is perfectly safe and harmless in trained hands.

Sonohysterography Sonohysterography is a special kind of ultrasound exam. Fluid is put into the uterus through the cervix using a thin. plastic tube. Sound waves are then used to create images of the lining of the uterus. The fluid helps show more detail than. when ultrasound is used alone. This test can be done in your obstetrician–gynecologist’s (ob-gyn) office, a hospital, or. a clinic.

- Test Overview. An abdominal ultrasound uses reflected sound waves to produce a picture of the organs and other structures in the upper abdomen. Sometimes a specialized ultrasound is ordered for a detailed evaluation of a specific organ, such as a kidney ultrasound. An abdominal ultrasound can evaluate the: Check the size, shape, and position of the liver. 2  An ultrasound may be done to evaluate jaundice and other problems of the liver, including liver masses, cirrhosis, fat deposits in the liver (called fatty liver), or abnormal liver function tests.

Fetal Ultrasound Fetal ultrasound is a test done during pregnancy that uses reflected sound waves to produce a picture of a fetus, the organ that nourishes the fetus (placenta), and the liquid that surrounds the fetus (amniotic fluid). The picture is displayed on a TV screen and may be in black and white or in color. 2nd-trimester fetal ultrasound is done to: 2  Estimate the age of the fetus (gestational age). 3  Look at the size and position of the fetus, placenta, and amniotic fluid. 4  Determine the position of the fetus, umbilical cord, and the placenta during a procedure, such as an amniocentesis or umbilical cord blood sampling.

Medical Dictionary Why It Is Done. For men and women, pelvic ultrasound may be done to: 1  Find the cause of blood in the urine (hematuria). 2  An ultrasound of the kidneys may also be done. 3  Find the cause of urinary problems. 4  Look at the size of the bladder before and after urination. pelvic ultrasound looks at the bladder and: 1  The ovaries, uterus, cervix, and fallopian tubes of a woman (female organs). 2  The prostate gland and seminal vesicles of a man (male organs).

- An ultrasound scan, also referred to as a sonogram, diagnostic sonography, and ultrasonography, is a device that uses high frequency sound waves to create an image of some part of the inside of the body, such as the stomach, liver, heart, tendons, muscles, joints and blood vessels.ltrasound is used to create images of the fetus or embryo in the uterus. Today, often referred to simply as an ultrasound scan, it is part of standard prenatal care.

Ultrasound Summary. Ultrasound is a type of imaging. It uses high-frequency sound waves to look at organs and structures inside the body. Health care professionals use it to view the heart, blood vessels, kidneys, liver, and other organs. During pregnancy, doctors use ultrasound to view the fetus.

Digestive Problems and Ultrasound Testing Ultrasound is used to create images of soft tissue structures, such as the gallbladder, liver, kidneys, pancreas, bladder, and other organs and parts of the body. Ultrasound can also measure the flow of blood in the arteries to detect blockages. Ultrasound testing is safe and easy to perform.

What is ultrasound (ultrasonography)? Ultrasound is very useful for looking at soft tissue parts of the body such as the kidneys and bladder. Soft tissues do not show up well on x-ray. Your baby or child may have a renal ultrasound to: 1  find out if there are any blockages in the urinary tract (kidney, ureter, bladder and urethra).

Diagnostic Ultrasound Ultrasound is a popular cost effective imaging tool. High frequency sound waves travel from the ultrasound probe through human tissue. Some of the sound waves bounce back to the transducer. This reflected sound is used by a computer to form the ultrasound image. There is no radiation dose associated with the ultrasound scan. Ultrasound is the examination of choice in obstetrics.

Ultrasound Ultrasound is an imaging modality that utilizes high-frequency sound waves to provide cross-sectional images of the body. The ultrasound machine has the following components: monitor, keyboard, processor, data storage and probe or transducer. A transducer performs two functions: it emits sound waves (echoes) at a certain frequency and captures the returning echoes at frequencies dependent on the tissues through which the waves traverse. The sound wave that is returned to the transducer is digitized to appear as echoes or dots on the screen.

- Fetal ultrasound is usually done by an ultrasound technologist or doctor in a doctor's office, hospital, or clinic. An early fetal ultrasound is one that is done before 18 to 20 weeks of pregnancy. The test takes 15 to 60 minutes. If the test doesn't show any problems, you may feel more at ease during your pregnancy. If the test shows that you are carrying more than one baby, you can plan ahead for a healthy pregnancy and delivery.

What is an ultrasound? An ultrasound technician, called a sonographer, will apply a special lubricating jelly to your skin. This prevents friction so they can rub the ultrasound transducer on your skin. The transducer has a similar appearance to a microphone. The jelly also helps transmit the sound waves. The transducer sends high-frequency sound waves through your body.

Ultrasound Exams Ultrasound is energy in the form of sound waves. The most common type of ultrasound exam is called two-dimensional (2D) ultrasound. In this type of ultrasound, a transducer sends sound waves through the body. The sound waves hit tissues, body fluids, and bones.

Digestive Problems and Ultrasound Testing Before the Ultrasound. Generally, no special preparation is needed for an ultrasound. Depending on the type of test, you may need to drink fluid before the ultrasound or you may be asked to fast for several hours before the procedure. During the Ultrasound. 1  You will lie on a padded examination table. 2  A specially trained technologist will perform the test. 3  A small amount of water-soluble gel is applied to the skin over the area to be examined. 4  A wand-like device called a transducer is gently applied against the skin. 5  You may be asked to hold your breath briefly several times. 6  The
