Sonogram vs. Ultrasound

Sonogram vs. Ultrasound

Oftentimes, the terms “sonogram” and “ultrasound” are used interchangeably. However, there’s a difference between the two:

  • An ultrasound is a tool used to take a picture.
  • A sonogram is the picture that the ultrasound generates.
  • Sonography is the use of an ultrasound tool for diagnostic purposes.

In short, an ultrasound is the process, while a sonogram is the end result.

What Is an Ultrasound?

An ultrasound is a non-invasive medical imaging scan that uses high-frequency sound waves — called ultrasound waves —to produce images of organs, soft tissues, blood vessels, and blood flow, from inside the body. These images are used for medical analysis.

After x-ray exams, ultrasound is the most commonly used form of diagnostic imaging. It helps doctors gain insights into the inner workings of the body, and is known for being:

  • safe
  • radiation free
  • noninvasive
  • portable
  • widely accessible
  • affordable

How does ultrasound work?

Ultrasounds use high-frequency sound waves that are beamed into the body and bounce back (echo) off tissue and organs. These echoes generate electrical signals that are translated by a computer to produce images of the tissues and organs.

Variations of ultrasound include:

  • Doppler ultrasound can be used to measure and visualize blood flow in the heart and blood vessels.
  • Elastography is used to differentiate tumors from healthy tissue.
  • Bone sonography is used to determine bone density.
  • Therapeutic ultrasound is used to heat or break up tissue.
  • High intensity focused ultrasound (HIFU) has been designed to destroy or modify abnormal tissue in the body without opening the skin.

Most ultrasounds are done using a transducer on the surface of the skin. At times, a better diagnostic image can be generated with the insertion of a special transducer into one of the body’s natural openings: vaginal, anal, or esophegael. 

What is a Sonogram?

A sonogram (also called an ultrasonogram) is the visual image produced during an ultrasound examination. A medical sonographer — often referred to as an ultrasound tech — is the person trained to use ultrasound diagnostic imaging technology (sonography). They provide doctors with detailed images of what’s going on inside of patients.

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.

Ultrasound is considered a safe and affordable imaging technology to help a doctor make a diagnosis regarding soft tissue and organs in the body.

Unlike x-rays, ultrasounds don’t use any radiation. An ultrasound can also show parts of the body in motion, such as a heart beating or blood flowing through blood vessels.
