Ultrasound Dating Accuracy

The Diagnostic Sonography more commonly known as Ultrasound is a medical procedure in which you use high frequency sound waves to produce visual images of organs tissues or blood flow inside the body. Ultrasound is regularly known as the procedure used to examine women who are expecting. Although, Sonography is used in many different ways other than for expectant mothers. Sonography is also used to detect such things as heart disease, heart attacks, and vascular disease that can lead to stroke. (SDMS, 2010) Moreover, Sonography is also used to examine breasts, abdomens, female reproductive systems,

Ultrasounds continue into Obstetric and Transvaginal. Obstetric is the use of ultrasound scans in pregnancy (Woo, Dr. Joseph S.K). Transvaginal are used to capture more precise images in patients who are obese and/ or in the early stages of pregnancy and is conduction through the vaginal cavity (Woo, Dr. Joseph S.K).

Most ultrasounds are done using a transducer on the surface of the skin. Sometimes, however, doctors and technicians can get a better diagnostic image by inserting a special transducer into one of the body's natural openings

Christine Le, an accountant living in Flushing, New York, gave birth to a healthy baby “Nathan” on January 29th, 2010. She found out that she was pregnant with her first child when her period was late. She had the routine prenatal care starting at 12 weeks and delivered at 40 weeks in a hospital with the present of her husband, Robert, and the in-laws. To insure her baby was healthy, Christine underwent several prenatal diagnostic methods like amniocentesis to examine for genetic defects. Another method was ultrasound; its purpose is to assess fetal age, multiple pregnancies, size and shape of the fetus. Christine underwent numerous lab tests to ensure that there are no complications (Berk, pg.43). Lab tests like a complete blood count that screens

Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through the use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in the diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies

Also, using an ultrasound is a great way to make sure that everything is okay with the mother during the pregnancy. The doctor can also see if there is more than one fetus and the gender of the fetus to prepare the parents for what they will need to be gathering for the future.

Diagnostic medical sonographers play a key role in the health care team and often work alongside doctors, nurses, and other technologists. They prepare patients by explaining the procedure and collect necessary patient history information prior to examination. An ultrasound is then performed, which is a non-invasive process that enables sonographers to send high-frequency sound waves into the body. The return signals are then analyzed to help visualize internal organs in 2D, 3D or 4D. These images help physicians with medical diagnoses and are also used for monitoring pregnancy. An ultrasound is often executed on many different areas of the body including the abdomen, pelvis, tissues, and vascular and cardiac systems. A DMS may also be required

The Ultrasound technician will facilitate the abdominal ultrasound to produce images of the organs for interpretation.

My freshman year of high school, I displayed symptoms of appendicitis and an ultrasound had been requested by my doctor. I was pleasantly surprised to discover that ultrasounds were not just for when you were expecting a little one, they serve diagnostic purposes as well. Interested, I researched the different fields of ultrasound sonography and had a specific attraction to obstetric sonography. Obstetric sonography, is specialized in capturing the inside of a woman’s uterus and reveal the growth and development of an embryo or fetus if she is pregnant.

Typically, these ultrasounds are performed with an outside company that is not related to the woman's doctor. This is a great option because the women will not need to worry about getting a referral from their doctor and can schedule the ultrasound whenever is convenient for them. Many businesses even offer appointments in the evening and on weekends for added convenience.

The accuracy of the ultrasound calculation of the gestational age varies as indicated by the gestational age. "Ultrasound measurement of the embryo or fetus in the first trimester (up to and including 13 6/7 weeks of gestation) is the most accurate system to establish or affirm gestational age" [24].

Currently, there are four prenatal diagnosis techniques used. The first, and safest method, is an ultrasound. It is noninvasive and can assess and evaluate gestational age, fetal position, growth, development, and any structural birth defects. When performed by highly skilled operators, abnormalities can be detected with as high as 90% accuracy (IOM 1994).

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,
