Radiology Diagnosis | Ultrasound Scan

What is an ultrasound scan?

The person performing the test puts a small amount of gel and applies a probe in contact with the skin on the area to be examined. This probe will send out ultrasounds that will go through the body tissues. As they penetrate the structures of the body, part of the ultrasounds are reflected and detected by the probe that is in contact with the skin.

The ultrasound scan will construct an image from the reflected ultrasounds. The acquisition of the image is done in real time, obtaining great quality studies that even enable to study the movement of internal organs (like the heart) and muscles.

It is widely used for performing lesion punctures or abscess drainage since you can see the image in real time.

 

What is the purpose of the gel?

The gel is necessary for both a good transmission of the ultrasounds to the body and for a good reception to the ultrasound scan.

What can be studied through an Ultrasound scan?

Except for bones, everything can be studied through an ultrasound.

 

Can you see the vessels? What is a Doppler Ultrasound?

The Doppler ultrasound is a modality that studies the blood flow. Through advanced calculations of the ultrasound scan we can know the direction and velocity of the blood, which will allow us to make assessments from the leg veins (study of thrombosis or vein insufficiency) to the neck arteries.
