What will I experience during and after the procedure?
Most CT exams are painless, fast and easy. With spiral CT, the amount of time that the patient needs to lie still is reduced.
Though the scanning causes no pain, there may be some discomfort from having to remain still for several minutes. If you have a hard time staying still, are claustrophobic or have chronic pain, you may find a CT exam to be stressful.
If an intravenous contrast material is used, you will feel a slight pin prick when the needle is inserted into your vein. You may have a warm, flushed sensation during the injection of the contrast materials and a metallic taste in your mouth that lasts for a few minutes. Occasionally, a patient will develop itching and hives, which can relieved with medication. If you become light-headed or experience difficulty breathing, you should notify the technologist, as it may indicate a more severe allergic reaction.
If the contrast material is swallowed, yhou may find the taste mildly unpleasant; most patients can easily tolerate it.
You will be alone in the exam room during the CT scan, however, the technologist will be able to see, hear and speak with you at all times.With pediatric patients, a parent may be allowed in the room but will be required to wear a lead apron to prevent radiation exposure.
After a CT exam, you can return to your normal activities. If you received a contrast material, you may be given special instructions.
