What is an ultrasound and how does it work?

Also known as sonography, ultrasound imaging uses a small transducer (probe) to both transmit sound waves into the body and record the waves that echo back. Sound waves travel into the area being examined until they hit a boundary between tissues, such as between fluid and soft tissue, or soft tissue and bone.

What are 3 uses of ultrasound?

Doctors commonly use ultrasound to study a developing fetus (unborn baby), a person’s abdominal and pelvic organs, muscles and tendons, or their heart and blood vessels. Other names for an ultrasound scan include sonogram or (when imaging the heart) an echocardiogram.

Is ultrasound a radiation?

Unlike X-ray imaging, there is no ionizing radiation exposure associated with ultrasound imaging. In an ultrasound exam, a transducer (probe) is placed directly on the skin or inside a body opening.

What is done during an ultrasound?

The transducer sends sound waves into your body, collects the ones that bounce back and sends them to a computer, which creates the images. Sometimes, ultrasounds are done inside your body. In this case, the transducer is attached to a probe that’s inserted into a natural opening in your body.

What are the benefits of an ultrasound?

Benefits of Ultrasound

  • They are generally painless and do not require needles, injections, or incisions.
  • Patients aren’t exposed to ionizing radiation, making the procedure safer than diagnostic techniques such as X-rays and CT scans.
  • Ultrasound captures images of soft tissues that don’t show up well on X-rays.

Is an ultrasound painful?

Unlike some other scans, such as CT scans, ultrasound scans don’t involve exposure to radiation. External and internal ultrasound scans don’t have any side effects and are generally painless, although you may experience some discomfort as the probe is pressed over your skin or inserted into your body.

What are the types of ultrasound?

Types of Ultrasound

  • Endoscopic ultrasound.
  • Doppler ultrasound.
  • Color Doppler.
  • Duplex ultrasound.
  • Triplex ultrasound (color-flow imaging)
  • Transvaginal ultrasound.

What is an ultrasound machine used for?

An ultrasound machine makes images so that organs inside the body can be examined. The machine sends out high-frequency sound waves, which reflect off body structures. A computer receives the waves and uses them to create a picture.

Is ultrasound harmful to humans?

Although Ultrasound cannot be heard by humans, at high decibels it can still cause direct damage to human ears. Ultrasound in excess of 120 decibels may cause Hearing damage. Exposure to 155 decibels causes heat levels that are harmful to the body. 180 decibels may even cause death.

What are the disadvantages of ultrasound?

Disadvantages of ultrasonography include the fact this imaging modality is operator and patient dependent, it is unable to image the cystic duct, and it has a decreased sensitivity for common bile duct stones.

What is the side effect of ultrasound?

Risks and Contraindications While the energy of the ultrasound waves could potentially irritate or disrupt tissues with prolonged exposure, the computer modulates the power of the sound and a trained technician uses techniques to minimize exposure times and angles. So, sonography is the safest of the imaging tests.

Who can perform ultrasound?

Till now, only gynaecologists and radiologists with post-graduate medical qualifications were allowed to perform ultrasound sonography on pregnant women. The Act also allowed MBBS doctors with six months’ training to conduct sonography but there had been a lot of ambiguity about the training aspects.

How long should an ultrasound take?

An ultrasound test usually takes 30 minutes to an hour. During the test, a trained professional: Applies gel: You’ll have a small amount of water-soluble gel on your skin over the area to be examined.

Do you get ultrasound results immediately?

How long will it take for my doctor to receive the results of my ultrasound exam? One of our board-certified radiologists will review and interpret your ultrasound results immediately. Your doctor will receive a written report and hardcopy images within 24 hours.

How do you read an ultrasound picture?

Determine the visible side of the body. Most ultrasound images are mirrored, meaning you see the left side of the body on the left side of the image. If you have a transvaginal ultrasound, though, it uses a straight shot. A straight shot will show the left side of the body on the right side of the image.
