Examination preparation

Computer tomography (CT)

The examination is carried out either with or without a contrast medium, depending on the question. The contrast medium is injected into a vein in the elbow, the forearm or the back of the hand (intravenous contrast medium). Computer tomography is not suitable for pregnant women.

If you are informed that a contrast medium is required when you make the appointment or in the discussion with the doctor,, we require the following up-to-date laboratory values:

  • Serum creatinine (laboratory value) as a measure of kidney function
  • TSH as a measure of thyroid function

For examination of the abdominal area, in addition to the intravenous contrast medium, it may be necessary for you to also drink a contrast medium to enable good imaging of the stomach and intestines. If required, this will be considered when making the appointment.

Sonography (Ultrasound) of abdominal organs

Sonography (Ultrasound) of abdominal organs

For optimal image quality, it is important that the examination is carried out on an empty stomach. We therefore ask you to refrain from eating on the morning of the appointment and at most to drink a small glass of liquid. In case of known diabetes and adherence to a special diet, you should consult your doctor beforehand.

Sonography of all areas except the abdomen

No special preparations are usually required for all other sonography examinations.

Digital X-Ray

of the spine, joints, lungs

No special preparations. X-ray examinations cannot be carried out on pregnant patients. The images are made and results discussed during the normal opening times of the X-ray department.

Magnetic resonance tomography (MRT, magnetic resonance imaging)

Depending on the question, MRT examinations are carried out with or without a contrast medium. Whether or not a contrast medium is required will be decided before or during the examination. Because of this, we require the

  • serum creatinine (laboratory value) as a measure of kidney function

The findings should not be more than three months old on the day of examination.

Under certain circumstances, an MRT cannot be carried out:

  • On patients with pacemakers or defibrillators
  • In case of particular electronic devices in the body, for example cochlear implants, insulin pumps, heart pumps, pain relief and simulation catheters
  • In case of old metallic operation clips in the head
  • In case of metal fragments or parts in critical parts of the body
  • On patients in the early stages of pregnancy (especially in the first 3 months)
  • In case of doubt, please contact our reception in advance, so that an alternative to the MRT examination can be found if necessary.
