Ultrasound vs Sonography: Difference and Comparison

Because of the changes in our lifestyle, our internal organs get damaged. Without ultrasound and sonography devices it is very hard to find the problem.

They are performed by certified professionals who excel in that area. This report helps our doctors to understand the problem in our body so that they can start the right treatment and give the best results.

Key Takeaways

  1. Ultrasound is a diagnostic imaging technique that uses high-frequency sound waves, while sonography interprets and analyses ultrasound images.
  2. Ultrasound devices generate images of internal body structures, while sonographers are trained professionals who evaluate these images for diagnostic purposes.
  3. Ultrasound is widely used in various medical fields, such as obstetrics, cardiology, and radiology, while sonography focuses on studying ultrasound images.

Ultrasound vs Sonography

Ultrasound is used to visualize various internal organs and structures, such as the uterus, ovaries, liver, gallbladder, and heart. Sonography is the process of performing an ultrasound examination by using an ultrasound machine and a transducer for internal scans of organs.

What is Ultrasound?

It is an imaging test. It uses waves for creating pictures of tissues, organs, and other structures of the body. The best part about ultrasound is they don’t use any radiation. It is done externally on the outside of the body.

People won’t feel any pain during this procedure and the only feeling they would get is the temperature of the translucent gel that is applied to the body for moving the transducer. Apart from that, the pain is virtually non-existent.
