Echography vs. Ultrasound: Know the Difference
By Shumaila Saeed || Updated on February 24, 2024
Echography and ultrasound both use high-frequency sound waves for internal body imaging. "Echography" focuses on echo-based imaging, less common in some areas, while "ultrasound" is a globally recognized term for the technology and procedure.
Key Differences
Echography is primarily used in certain European countries and contexts, the term focuses on the echo-producing aspect of the technology, highlighting how sound waves are reflected back to create an image. On the other hand Ultrasound is a universally accepted term that describes both the method and the equipment used to capture internal images of the body. It is recognized in medical practices worldwide.

The procedure for both echography and ultrasound involves applying a conductive gel to the skin and moving a transducer over the area of interest. The device emits sound waves that bounce off bodily structures and are captured to create an image. Interpretation of the images requires specialized training, as it involves understanding the variations in echo patterns that represent different types of tissues or abnormalities.
