Preparing for your exam — what you need to know
Which exam?
Make sure you know exactly which type of scan you need so that your booking process goes smoothly.
Medical referral
A referral is mandatory for a CT scan (Computed Tomography). It is not required for self-paid private MRI scans (Magnetic Resonance Imaging).
Payment options
Depending on the facility, we provide scans under the National Health Fund (NFZ), as self-paid private services, and for private health insurance holders.
Documents
Please bring your ID card and previous medical records – especially prior diagnostic imaging descriptions and CD/DVD discs.

Contrast required? Please fast before the exam: no food for at least 4 hours, no drinks for 2 hours.
- Bring your ID card and previous test results (CD/DVD discs).
- Remove all metal objects (jewelry, watch, hearing aid).
- Inform the medical staff about any implants, pacemakers, or foreign objects in your body.
Important (Implants and metal elements in the body): Certain metal elements can be a strict contraindication for the scan. Please note that we may ask you to provide an official certificate stating there are no contraindications for the MRI examination.
Contrast-enhanced scan: In some cases, we will request a recent blood test result for creatinine levels (the result must not be older than 30 days).

Additional procedures for patients taking metformin
Additional procedures for patients taking metformin
Patients with eGFR > 30 ml/min/1.73 m² (with no evidence of AKI) receiving intravenous or intra-arterial contrast media with secondary renal exposure:
Clinical recommendation: Metformin medication should be continued as normal.
Patients classified into renal risk groups:
- Criterion (a): with an eGFR < 30 ml/min/1.73 m² receiving intravenous or intra-arterial contrast media with secondary renal exposure.
- Criterion (b): receiving intra-arterial contrast media with primary renal exposure.
In the above cases (a and b), an individual consultation with the referring physician is recommended to verify the medication dosage prior to the examination.
(c) Patients with Acute Kidney Injury (AKI):
The absolute clinical procedure requires discontinuation of metformin from the time of contrast media administration. Subsequently, eGFR must be re-evaluated within 48 hours — the medication can only be restarted if renal function has not significantly changed.
