Sonogram vs. Ultrasound: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on January 5, 2024
A sonogram is an image produced by ultrasound, while ultrasound is the technology that uses sound waves to create images of the inside of the body.
Key Differences
A sonogram is the visual image produced from the sound waves generated during an ultrasound procedure. Conversely, ultrasound refers to the actual technology and process that uses high-frequency sound waves to create images of structures inside the body.
Sonograms are the end product, the images used by medical professionals to diagnose and monitor conditions. Ultrasound, however, is the method or procedure of using sound waves to generate these diagnostic images.
In a sonogram, the quality and clarity of the image depend on various factors such as the machine's quality and the technician's skill. In ultrasound, the focus is on the technique of emitting sound waves and capturing their echoes to form an image.
Sonograms are primarily used for examining internal organs, monitoring pregnancy, and diagnosing conditions. Ultrasound is the broader term encompassing the entire process, including the equipment, procedure, and the expertise required to interpret the sound waves.
It's a common misconception to use the terms sonogram and ultrasound interchangeably. A sonogram is the result (the image), while ultrasound is the process of imaging.
