Are an ultrasound and Sonogram the same thing? An ultrasound and a sonogram are part of the same examination, but they do mean different things.

A Sonogram

A sonogram is an image that is produced by ultrasound. The sonogram is the printed black and white image showing the foetus in the uterus, this is the image is that you get to take home from the ultrasound scan.

Other words associated with sonogram are “sonography” this refers to the practice of using an ultrasound machine to create the sonogram, a “sonographer” is the skilled person who operates the equipment.

A sonogram is produced by sound waves, the sonographer will send the sound waves using a transducer, this is a wand-shaped device, it is pressed on the body and the sound waves will then bounce back once they contact the tissues that are being looked at, they will travel through the transducer and enter the ultrasound computer. The ultrasound computer will then process the sound waves and turn them into an image which will appear on the screen. This will be the scanned image that you will be able to take home and show your friends and family.

An ultrasound

An ultrasound is a type of imaging test, it uses high-frequency sound waves to produce images, the ultrasound procedure is safe, painless, and non-invasive. The ultrasound machine will include a computer, monitor, printer, and a handheld transducer.

An ultrasound examination works by a sonographer applying gel onto the tummy, the gel helps remove air and connects the transducer to the skin, the soundwaves will then travel directly to and from the transducer. The sound waves will bounce off the tissues, fluids and organs, the pitch and direction of the sound waves will be picked up by the transducer and measured instantly and displayed on the computer.
