Yes, echography and ultrasound are the same thing. Echography is a term that is more commonly used in Europe, while ultrasound is the more commonly used term in the United States. Both terms refer to the use of high-frequency sound waves to produce images of internal body structures, such as organs, blood vessels, and developing fetuses.
Echography is a non-irradiating examination using ultrasound. Simple to perform and painless, ultrasound uses several modalities such as 2D, 3D with pulsed or colour doppler. Nothing could be easier for the patient: simply lie down on a dedicated table and the radiologist performs the examination.
