Ultrasound VS Sonogram

The terms “sonogram” and “ultrasound” are often used interchangeably. While people will generally understand what’s meant regardless of which word is used, technically they’re not synonyms.
An ultrasound is a simple, radiation-free, non-invasive procedure. Many people are familiar with it from its use during pregnancy to provide doctors with an image of the fetus in a mother’s womb.
A sonogram is an image produced by an ultrasound procedure. The term sonogram loosely translates as “sound writing,” since the sound waves effectively “write” the image that’s produced.
