CT, CT examination

What is a CT scan?

The CT.device uses X-rays to take pictures of specific areas of the human body. The images are evaluated by a radiologist within 3 working days of the examination. A CT scan can answer questions that cannot be answered by other diagnostic imaging methods such as ultrasound, X-ray or MR. Our clinic is equipped with a 128-slice GE Revolution Evo CT scanner with state-of-the-art software, one of the fastest in the world.
Its equipment and speed make it suitable for scans of the skull, neck, chest, lungs, abdomen, pelvis, spine, vascular system, extremities and heart. The examination is painless and safe. It takes a short 10-20 minutes in the exam room. Low radiation exposure to the human body. It can also be performed on patients with pacemakers. Accurate, reliable diagnostic procedure.
Because of the X-rays used, CT scans are only performed on the basis of a referral or written recommendation from a doctor, who will specify the region to be scanned and decide whether contrast material is needed. However, a low-dose chest CT scan is also available on request as a screening test.

The CT scan procedure

• CT scans are performed in the supine position, following the instructions of the operators performing the scan.
• The examination of a given region takes 15-20 minutes, during which immobility is required.
• The CT scan is painless and does not cause a feeling of confinement, as the examination table moves in a doughnut-shaped ring. The procedure is not accompanied by loud noise.
• CT scans can be performed either natively, i.e. without contrast agent, or with contrast agent.
• In the majority of cases, a native series without contrast is obtained first, followed by the injection of intravenous contrast and a repeat series of the same region.
• For abdominal and pelvic examinations, please always arrive on an empty stomach. Prior to abdominal and pelvic examinations, a special fluid intake is used to prepare for imaging of the digestive organs.
• Contrast material is administered by means of a vein, a venous cannula is placed in the arm or hand area through which contrast material is injected at the time of the examination.
• After contrast agent tests, you must remain in the institute for 30 minutes of observation from the time of injection.

What to know about CT scans

• CT scans can be carried out at any age on referral or recommendation, subject to the rules on ionising radiation.
• CT scans with anaesthesia and CT angiography of the extremities are not performed.
• We do not accept clients over 180 kg.
• Information about contrast media
• In case of known contrast sensitivity or pregnancy or suspected pregnancy, the scan cannot be performed.
• If you have hyperthyroidism, an endocrinology recommendation no more than 3 months prior to the CT scan is required for contrast administration.
• When having a contrast CT scan, it is important that you arrive on an empty stomach, so avoid eating 4-6 hours before the appointment to reduce nausea as a possible side effect of the contrast agent.

If intravenous contrast material is to be administered, the kidney function should be checked before administration. This is done by taking a blood sample from the laboratory. Please bring a laboratory report with you that is no more than 2 weeks old. The following parameters will be tested on the blood test: creatinine, urea, eGFR. The laboratory test can also be performed at our clinic. Please book an appointment!
