What is a CT scan?A CT scan uses X-rays to produce cross-sectional images of the body, which can be used to examine a specific body part.
About the examination
Preparing for the procedurePreparations for the CT scan start the day before the procedure is scheduled to take place. Find out which clothes you should wear, what to do if you are pregnant or breastfeeding, what to do if you take medication or have a stoma and the preparations you can expect in the waiting room. read more
Preparing for the procedure
If you are pregnant or if you think you may be pregnant, please contact your attending physician. We will decide, in consultation with you and the radiologist, whether the procedure can be carried out as scheduled or whether it should be postponed or replaced with an alternative procedure.
Eating and drinking
You are not allowed to eat or drink one hour before the procedure (you may continue to take your medication as usual). We recommend having a light breakfast or lunch on the day of the CT scan.
It is more convenient for you and for us if you wear comfortable, loose-fitting clothing that is easy to slip on and off. Depending on the type of procedure, you may be asked to remove garments that contain metal.
Your attending physician may ask you to temporarily discontinue the use of certain medications. In most cases, however, you can continue taking your medication as usual. We do ask that you bring an up-to-date medical passport with you, which you can request for free from your pharmacy.
If you think you may need extra time and/or attention during the procedure due to a disability, please let us know in advance. We will take this into consideration as much as possible.
If you have a stoma, we recommend taking an extra stoma bag with you. If you have an ileostomy, please notify the employee who brings you your water. In this case, you will be given less to drink.
In the waiting room
The first part of the procedure starts in the waiting room, where you will be asked to drink between 500 ml and 1 litre of water. In some cases, you may be given a contrast solution to drink instead. You will have thirty to forty-five minutes to drink the water or contrast solution. If you are on a fluid restriction diet, please notify the employee who brings you your water. In this case, you can drink what your diet allows.
You will then be picked up for the second part of the procedure: inserting the IV and administering the CT scan. This will take twenty minutes. The entire procedure will take approximately one hour.
What does the procedure entail?After you've finished your water in the waiting room, we will pick you up for the procedure. We may ask you to remove some of your clothes. read more
What does the procedure entail?After you've finished your water in the waiting room, we will pick you up for the second part of the procedure. (In some cases, you may be given a contrast solution to drink instead of water.) We may ask you to remove some of your clothes so that no metal is visible in the image. Once the IV has been inserted, you will be slid into the ‘ring’ of the CT scanner on the examination table. This tunnel is 70 cm in diameter and 50 cm deep and is where the images are taken. We will ask you to hold your breath several times.
The entire procedure takes roughly an hour, from the time you enter the waiting room until the CT images are taken.
After the procedureyou might experience loose stools. read more
After the procedureIf you were given water to drink, you probably won't experience loose stools.
If you were given a contrast solution to drink, you may experience loose stools for one or two days.

Radiology report or treatment in MijnRadboudWhen the procedure or treatment is finished, the radiologist will assess the images. Sometimes this happens the same day, sometimes a few days later. He or she will write a report and send it to your attending physician, who will read it carefully. Your physician will use the report and any other relevant examinations to reach a conclusion. You can review your radiology report (without images) in MijnRadboud. The report will be available seven days after the radiologist submits it. In MijnRadboud, click on the tab ‘MijnDossier’ (My File) and then on ‘Uitslagen’ (Results) to see your report. Your physician will discuss the results of this report with you during your next appointment.
As there may be some time between carrying out the procedure and drafting the report, we cannot guarantee that the results will be available in MijnRadboud seven days after your procedure. It takes seven days plus the time the radiologist needs to draft the report.
Scientific studyIf your procedure is being carried out as part of a scientific study, the results will not be published in MijnRadboud.
