Though it can be performed for all age groups, children are only examined in highly reasonable cases, due to the fact that X-radiation is used. In pregnancy the examination is also performed only in special cases.
Depending on the clinical situation, its frequency should be discussed with the physician.
Images are acquired via X-ray thus patients are exposed to radiation exposure. CT examination should be performed if the information content recieved after the examination is more beneficial for the patient health than the risk of the radiation exposure. Rarely, contrast material administered intravenously during CT scan and it may cause an allergic reaction. These are generally mild, but in extremely rare cases severe complication may occur. Always inform your doctor if you had any kind of reaction after using an iodinated contrast material. Chances of contrast material induced side effects are higher, if the patient has heart disease, asthma, diabetes, kidney or thyroid disease. The patient should always inform the radiologist about these conditions.
If requested by the physician, the examination needs referral of a physician (excluding a general practitioner). In this case, the examination is made according to the booking period and paid by the National Health Insurance Fund. The patient can also pay for the examination according to our pricelist. In the later case the examination is made in a significantly shorter waiting time. If you would like the examination yourself, please consult your doctor to find out whether this it is needed or not.
There are no side effects except for the possible contrast induced reactions.
The CT scanner is similar to a big, wide ring with a table moving in its lower side. The patient is lying on this table during the whole period of the examination. The device is quite loud during its normal operation. The most modern multi-detector devices make a sound similar to a smaller airplane when preparing to take off. Do not be frightened of this noise. The CT examination is itself painless, but most of the times it is necessary to administer intravenous contrast material, which means an intravenous injection. Though the scan lasts for a relatively short time, moving or breathing is prohibited, because movements and breathing can make the images more or less unassessable. Our colleague will tell you through a microphone exactly when you should stop breathing.
Our colleague will ask you to lie on the table, afterwards the table will start sliding into the wide ring. Then you should stay still for a short time. If our colleague asks you, you should hold your breath as well. In most cases intravenous contrast material is administered before the second scan. If necessary, subsequent scans will be carried out.
In case of abdominal-pelvic routine CT examinations, 1.5-2 liters of liquid should be consumed prior to the actual scan in 1-1.5 hours to differentiate the bowels. This liquid can be diluted iodinated or barium contrast material, water or a non-absorbing material solved in water. The pace of consumption is instructed by our colleague. It is important to strictly follow these instructions. The consumed great amount of liquid may cause diarrhea. It is common, do not be alarmed.

Fasting is required 4-6 hours before the CT examination, however abundant amount of gas free water or tea should be consumed. If you have diabetes, and you are taking medications (Adimet, Adebit, Meglucon, Metformin, Metrivin, Mercformin(BMS), Siofor, Meforal, Gluformin, Metfogamma, Avandamet, Euceras, Jamuvia, Janumet, Velmetia) for your disease, this medication should be skipped 2-3 days before and after the CT examination. You should consult your physician about how to keep your carbohydrate metabolism in balance during this time. You should take your other regular medicines before the CT examination.
Large bowel CT: cleaning of the bowel is necessary for the successful examination. A humane way of this is if the patient, after having a light breakfast on the day before the examination, won’t eat anything, while consuming a material for this purpose called X-Prep or Fleet-Phosphosoda and a lot of filtered, gas-free fluid.
5-15 minutes on the average. Examination of the heart takes 30 minutes.
