What is the Difference Between Sonogram and Ultrasound?

🆚 Go to Comparative Table 🆚

The terms "sonogram" and "ultrasound" are often used interchangeably, but they refer to different aspects of the same medical imaging process. Here are the key differences between the two:

  • Ultrasound: This is the procedure that uses high-frequency sound waves to create images from inside the body. It is a non-invasive, painless, and radiation-free imaging technique. Ultrasounds are used to examine various soft tissues and organs, such as kidneys, ovaries, liver, heart, and blood vessels.
  • Sonogram: This is the visual image produced during an ultrasound examination. It is the result of the ultrasound procedure and provides a picture of the internal structures of the body.

In summary, an ultrasound is the process of using sound waves to create images, while a sonogram is the image generated by the ultrasound procedure. Both terms are components of the same medical exam, and one cannot exist without the other.

Comparative Table: Sonogram vs Ultrasound

The terms "sonogram" and "ultrasound" are often used interchangeably, but they have distinct meanings:

  • Ultrasound: This refers to the procedure of using sound waves to create images of internal structures within the body, such as organs, blood vessels, and soft tissues. Ultrasounds are used for various diagnostic purposes and can produce real-time images.

  • Sonogram: This is the actual image produced by the ultrasound procedure. Sonograms are typically used during pregnancy to monitor fetal development and detect any potential issues. They can also be used to examine other organs and tissues in the body, such as the liver, kidneys, and heart.

Here is a table summarizing the differences between sonograms and ultrasounds:

Feature Ultrasound Sonogram
Definition Procedure Image
Purpose Create images of internal structures Result of the ultrasound procedure
Type of Images Real-time images Still images
Uses Various diagnostic purposes, such as examining the bladder, gallbladder, and heart Monitoring fetal development and detecting potential issues during pregnancy
Equipment Used Ultrasound machine and transducer probe Transducer probe
Results Provides real-time images of internal structures Shows the position, shape, and structure of organs and tissues on the screen

In summary, an ultrasound is the procedure that uses sound waves to create images, while a sonogram is the actual image produced by the ultrasound. The terms may be used interchangeably in some contexts, but they represent different aspects of the imaging process.
