During ultrasound examination, an ultrasound probe emits harmless sound waves. Depending on the type of fabric, the sound waves are reflected differently and picked up again by the transducer. The result is a real-time image that is viewed and interpreted directly on the monitor by the examiner.
With the help of the so-called duplex technique, the blood flow in the vessels can be visualized and any constrictions (stenosis) can be localized and their extent determined.
The most frequently examined organs are:
Abdominal cavity with liver, gallbladder, spleen
Pancreas, kidneys, lymph nodes and organs of the pelvis
Vessels of individual parts of the body
The ultrasound examination is completely painless and harmless. The doctor uses a gel on the patient's skin to optimize the image quality. Then the transducer is guided with gentle pressure over the areas of the body to be examined. The duration of the examination is about 5 to 10 minutes. The doctor will inform you about the results during the examination. If you have any additional questions, the radiologist is of course also available after the examination.
How do I prepare myself as a patient?
If you have an abdominal sonography, please come on an empty stomach. You should not eat or drink anything for a few hours beforehand. It is particularly advantageous during examinations of the pelvic organs not to empty the bladder beforehand. In all other examinations, there is nothing special to consider.
