Sonography

Ultrasound examinations have been a common method for many decades.

Sonography

General Information

More details on sonography

Sonography, also called ultrasonography, uses high-frequency ultrasonic waves for imaging. When they are sent into the tissues of the body, they are reflected in different ways by tissues with different structures. The reflected sound waves are recorded and measured – using the time difference between the sent and received impulses, the computer then generates an ultrasound image.

 

Advantages
Sonography is a radiation-free alternative to a normal X-ray examination. The application of a contrast medium is not required. The examination is completely painless and harmless, and can be carried out quickly.

 

Frequent applications
  • diagnostics of the abdominal and pelvic organs (liver, gall bladder, pancreas, spleen, kidneys and bladder)
  • examination of soft tissues and joints
  • examination of vessels (colour-coded duplex sonography)
  • examination of the mammary gland
  • examination for lymph node diagnostics
  • Colour-coded duplex sonography
Colour-coded duplex sonography is a special ultrasound examination for vascular diagnostics, in which blood flow can be imaged. Using the analysis of the blood velocity, significant constrictions in the vessels (vascular stenoses) and expansions (aneurysms) are indicated and can then be diagnosed.
Is the examination causing pain?

No, the examination is not causing any pain.

 

How is the examination carried out?
In a sonography examination, the doctor moves a transducer over you while an image of the examined region of the body is simultaneously displayed on the monitor.

 

How long does the examination take?
The length of the examination depends on the region of the body examined. However, it generally takes between 5 and 20 minutes.

 

How should I prepare for an examination of the abdominal organs?
We recommend that you don’t eat or drink anything in the last four hours before the examination of the abdominal organs, since air in the stomach and intestinal area can greatly reduce the quality of the examination and the image.

 

How should I prepare for an examination of the bladder?
For an examination of the pelvic organs (bladder), it is advantageous for your bladder to be full so that it can be used as a so-called acoustic window.

 

How should I prepare for an examination of the soft tissues or vessels?
No particular preparation is necessary for ultrasound examinations of the soft tissues or vessels.
