Ultrasound imaging (sonography) uses high frequency sound waves, to create a live video feed image of the inside of the body. ... Unlike X-ray imaging, there is no radiation exposure associated with ultrasound imaging. During an ultrasound exam, a probe called a transducer is placed directly on the skin or inside the body.

The difference between the two comes down to definitions of the two words. An x ray is a photon of energy. This is what is exposing the patient for the final image. ... A radiograph is the resultant image after a patient or object is exposed to x rays.

Ultrasound is often used to image muscles, internal organs, tendons, etc. ... The CT offers a much better image and it can be directed precisely at a target area. And because it is an image of many different angles, the doctor has a better view of the target area over a flat x-ray exposure.

Although these fields use completely different technology, both types of care providers use imaging techniques as a primary tool for their diagnosis. Ultrasound utilizes sound waves while the radiologist uses a variety of tools, including x-rays, ultrasound, radionuclides and other methods to help patients.

A fetal ultrasound (sonogram) is an imaging technique that uses sound waves to produce images of a fetus in the uterus. Fetal ultrasound images can help your health care provider evaluate your baby's growth and development and monitor your pregnancy.

You aren't exposed to ionizing radiation, so the procedure is safer than X-rays and CT scans. In fact, there are no known harmful effects when it's used as directed. Ultrasound captures images of soft tissues that don't show up well on X-rays. Ultrasounds are widely accessible and less expensive than other methods.

The echocardiogram is an ultrasound of the heart that provides moving pictures and provides information on the structure and function of the heart. The EKG is a heart tracing that mainly provides information on the rhythm of the heart. Both tests are often used in conjunction and are complimentary to each other.

Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. ... Ultrasonic devices are used to detect objects and measure distances.

An ultrasound is considered safe for both you and your baby when it's used for medical purposes. Although ultrasounds require no radition, only a trained professional who can interpret the results with accuracy should perform them.

The most significant difference between 3D and 4D ultrasound is that 4D allows physicians to “live stream” video of the baby's images. 4D ultrasound is essentially 3D ultrasound in live motion.

All medical procedures have risk. But, there's no evidence to show a prenatal ultrasound done properly will harm a mother or her unborn child. Done properly means it's performed by a physician or a trained technician, called a sonographer. Ultrasound does not use radiation, as other procedures, such as X-rays, do.

Most ultrasound scans last between 15 and 45 minutes. They usually take place in a hospital radiology department and are performed either by a radiologist or a sonographer.

A bone scan is the opposite of a standard X-ray in the way that it creates an image. During an X-ray, radiation is sent through your body to create an image on film placed behind your body. In a nuclear scan, your body is emitting the radiation to the surface where it can be detected by the gamma camera.

Forney says. MRI and ultrasound look at the body in different ways. MRI, which uses powerful magnets to produce 3-D anatomic images, is a high-contrast resolution modality that can determine changes in the tissue quality.

A level II ultrasound is similar to a standard ultrasound. The difference is that your doctor will get more detailed information. Your doctor may focus on specific parts of your baby's body, such as his or her brain, heart, or the other organs. You may get a targeted ultrasound in your second trimester.

The takeaway Although often used interchangeably, ultrasound is the procedure of using sound waves to create images from inside the body. Sonogram is the image produced by an ultrasound examination.

They have similar uses but produce pictures in different ways. CT scans use X-rays while MRI scans use strong magnets and radio waves. A CT scan is generally good for larger areas, while an MRI scan produces a better overall image of the tissue under examination. Both have risks but are relatively safe procedures.
