An ultrasound is a study which shows your interior body. In this technique sound waves are used. A transducer (a type of microphone) sends the sound waves. These waves are converted into moving images on a monitor. These images are pictures.
With an ultrasound it is possible to detect any abnormalities to your organs in your abdomen.
Preparation and instructions
An ultrasound scan of the upper abdomen
For an ultrasound of your upper abdomen it is necessary that your bowels are empty, to prevent the contents of the intestines affecting the imaging. Therefore, it is important to follow the instructions below.
The day before the ultrasound:
After midnight: don´t eat, drink or smoke
The day of the ultrasound:
If you have an appointment after 13:00 pm, you may have a light breakfast of two slices of toast and a cup of tea the morning of the ultrasound, at 8 o´clock. After the ultrasound, you may eat again.
An ultrasound of the lower abdomen
You should come to the appointment with a filled bladder. If this is not the case the radiologist can´t investigate your lower abdomen. This means that you have to drink some glasses of water approximately one hour before the ultrasound and can´t go to the toilet.
If you have a special diet, such as a diabetes diet, please contact the physician who requested the investigation.
You will be asked to lay on the examination table. The radiologist applies a cold gel on your upper stomach. With a transducer the radiologist scans your belly. The radiologist looks on the monitor if there are any abnormalities. This examination is not painful. Note: If the gel gets on your clothes, this is washable.
Duration of the examination
The results of the ultrasound will be sent within 24 hours to the physician who requested the investigation. Your doctor will give you more information.
