The sound creates the image
An ultrasound scan is a radiation-free medical imaging procedure. As a result of ultrasound waves in the inaudible range, two-dimensional live images are generated, conveying to the doctor via a monitor a view of the size, shape and structure of the area being examined.
An ultrasound is particularly well-suited to areas where there are no bones in the way. Common examples of usage for an ultrasound include:
- the soft tissues of the neck and thyroid
- internal organs
- in diagnosing cancer, for example in detecting metastases of the liver
Ultrasound examination procedure:
During an ultrasound scan, the region being examined will be undressed. The doctor will subsequently apply a water-based ultrasound gel to the skin. The doctor will then place the ultrasonic probe on the skin and is, depending on the support bracket, able to look at the required organs and tissues from different directions. The live images will be displayed on a monitor.
An ultrasound scan is radiation-free and painless. In general, a scan lasts from five to fifteen minutes.
